untreated hearing loss = dementia update

Untreated hearing loss in midlife remains the largest modifiable risk factor.

The study is an update to The Lancet Commission’s original 2017 report on dementia prevention, intervention, and care, and adds head injury and harmful alcohol drinking in midlife, and air pollution exposure in later life, to the list of preventable causes of dementia but Untreated hearing loss in midlife remains the largest modifiable risk factor.

RELATED ARTICLE: Nine Risk Factors Associated with Dementia, by Dennis Hampton, PhD

Combined, the three new risk factors are associated with 6% of all dementia cases—with an estimated 3% of cases attributable to head injuries in midlife, 1% of cases to excessive alcohol consumption (of more than 21 units per week) in midlife, and 2% to exposure to air pollution in later life. The remaining risk factors are associated with 34% of all dementia cases. The factors associated with the greatest proportion of dementia cases in the population are less education in early life, hearing loss in midlife, and smoking in later life (7%, 8%, and 5%, respectively).

Led by 28 world-leading dementia experts, the report builds on the nine risk factors identified in the 2017 Lancet Commission*, and provides an up-to-date analysis of the best evidence on the prevention of dementia. The new report calls for nations and individuals to be ambitious about preventing dementia and lays out a set of policies and lifestyle changes to help prevent dementia. The report was presented July 30, 2020 at the Alzheimer’s Association International Conference (AAIC 2020).

Lead author Professor Gill Livingston (UCL Psychiatry and Camden & Islington NHS Foundation Trust) said: “Our report shows that it is within the power of policymakers and individuals to prevent and delay a significant proportion of dementia, with opportunities to make an impact at each stage of a person’s life.

“Interventions are likely to have the biggest impact on those who are disproportionately affected by dementia risk factors, like those in low- and middle-income countries and vulnerable populations, including Black, Asian, and minority ethnic communities.

“As societies, we need to think beyond promoting good health to prevent dementia, and begin tackling inequalities to improve the circumstances in which people live their lives. We can reduce risks by creating active and healthy environments for communities, where physical activity is the norm, better diet is accessible for all, and exposure to excessive alcohol is minimized.”

Worldwide, around 50 million people live with dementia, and this number is projected to increase to 152 million by 2050. Dementia affects individuals, their families, and the economy, with global costs estimated at about US$1 trillion annually.

In certain countries, however, the proportion of older people with dementia has fallen, probably due to improvements in education, nutrition, healthcare, and lifestyle changes, demonstrating the possibility of reducing dementia through preventative measures.

To address dementia risk, the authors call for nine ambitious recommendations to be undertaken by policymakers and by individuals:

  • Aim to maintain systolic blood pressure of 130 mm Hg or less in midlife from around age 40 years.
  • Encourage use of hearing aids for hearing loss and reduce hearing loss by protecting ears from high noise levels.
  • Reduce exposure to air pollution and secondhand tobacco smoke.
  • Prevent head injury (particularly by targeting high-risk occupations and transport).
  • Prevent alcohol misuse and limit drinking to less than 21 units per week.
  • Stop smoking uptake and support individuals to stop smoking (which the authors stress is beneficial at any age).
  • Provide all children with primary and secondary education.
  • Lead an active life into mid, and possibly, later life.
  • Reduce obesity and diabetes.

These actions are especially important in low- and middle-income countries where dementia rates are rising more rapidly than in high-income countries, and around two-thirds of people with dementia live. This is a result of increasing life expectancy, and a higher frequency of certain dementia risk factors—such as lower rates of education; high rates of hypertension, obesity, and hearing loss, and rapidly growing rates of diabetes.

Study co-author Dr Naaheed Mukadam (UCL Psychiatry and Camden & Islington NHS Foundation Trust) said: “Based on our modeling, we expect that even more cases of dementia could be prevented in low- and middle-income countries, compared to wealthier countries, due to the higher prevalence of the risk factors we have identified. We had previously estimated that nine factors contribute to 35% of dementia cases worldwide, but that figure rises to 40% in China, 41% in India, and 56% in Latin America.”

The authors warn that estimates could be even higher, as they used conservative estimates for the prevalence of risk factors, and because they do not account for the three new risk factors.

Co-author Dr Jonathan Huntley (UCL Psychiatry and Camden & Islington NHS Foundation Trust) added: “Nearly all of the available evidence on dementia is from high-income countries, so there is an urgent need for more studies to be conducted in the rest of the world, to understand if risks differ elsewhere and if our solutions might need to be tailored to different cultures and environments.”

The authors note that the modeling for their prevention estimates assumes that there is a causal relationship between risk factors and dementia, but were careful to only include risk factors with strong evidence for a causal link.

In the final section of the report, the authors advocate for holistic and individualized evidence-based care that addresses physical and mental health, social care, and support that can accommodate complex needs.

Study co-author Dr Andrew Sommerlad (UCL Psychiatry and Camden & Islington NHS Foundation Trust) said: “Supporting the physical health of people with dementia is important for their cognition, but also because they may struggle to manage other illnesses, which can lead to preventable and potentially harmful hospitalizations.”

They note that people with dementia are particularly at risk from COVID-19 (due to age and having pre-existing illnesses, such as hypertension), and that physical distancing measures can be challenging for dementia patients, who may find it difficult to adhere to the guidelines or distressing to be unable to have contact with carers and family.

The authors call for people with unknown COVID-19 status to not be admitted to care homes to protect the existing residents, regular testing of staff and asymptomatic as well as symptomatic residents when there is exposure, not moving staff or residents between homes, and more research into how to protect dementia patients during the current pandemic and future public health emergencies.

The study was conducted by researchers in the UCL faculties of Brain Sciences and Population Health Sciences, alongside colleagues at other institutions in the UK, Nigeria, Australia, Israel, India, United States, France, Canada, and Norway. Lead partners with the Lancet were UCL, the Alzheimer’s Society, the Economic and Social Research Council, and Alzheimer’s Research UK.

UM SOM Study Announces Breakthrough in Understanding Hearing Loss

Study Pinpoints a Mechanism Behind Some Deafness

Researchers at the University of Maryland School of Medicine (UM SOM) today announced a breakthrough discovery that could eventually help scientists repair hearing problems or protect those at risk for hearing loss – a condition that affects some 40 million Americans.

In particular, with 74,000 children currently affected by profound, early-onset deafness, scientists have been trying to solve the mystery of what causes hearing disorders, especially those that may have genetic causes.

Now, the new UM SOM study, has identified a crucial protein in the process that turns sound waves into brain signals. The new understanding could eventually help repair or prevent hearing problems for those with the highest risk.

The findings were published recently in the Nature Communications. The study is the first to illuminate in detail how the protein, known as CIB2, enables hearing.

“We are very excited by these results”, said the senior author of the study, Zubair Ahmed, PhD, Professor in the Department of Otorhinolaryngology-Head and Neck Surgery at UM SOM. “This tells us something new about the fundamental biology of how hearing works on a molecular level.”

CIB2, which is short for calcium and integrin-binding protein 2, is essential for the structure of stereocilia, the structures at the top of the sensory hair cells in the inner ear. Stereocilia are extremely small, less than a half a micrometer in diameter, which is about the wavelength of a visible light. Each ear contains 18,000 hair cells that do not divide or regenerate.

Saima Riazuddin, PhD, MPH, MBA

Dr. Ahmed and his colleague Saima Riazuddin, PhDProfessor in the Department of Otorhinolaryngology-Head and Neck Surgery at UM SOM, along with their collaborators, discovered five years ago that CIB2 was involved in hearing. Since then, they have studied the protein in flies, mice, zebrafish and humans. The new study is the first to explain the mechanism behind CIB2 in hearing.

In this study, they genetically engineered mice without CIB2, as well as mice in which a human CIB2 gene mutation had been inserted. The researchers found that the human mutation affects the ability of the CIB2 protein to interact with two other proteins, TMC1 and TMC2, which are crucial for converting sound to electrical signals, a process known as mechanotransduction.

People with this mutation cannot turn soundwaves into signals the brain can interpret, and so are deaf. When the researchers inserted the human CIB2 mutation into the mouse, they found that the mice were deaf.

“This is a big step in determining the identity of key components of the molecular machinery that converts sound waves into electrical signals in the inner ear,”said the study’s co-senior author, Gregory Frolenkov, PhD, of the Department of Physiology at the University of Kentucky.

Dr. Ahmed and his colleagues are now looking for other molecules beyond CIB2 that play a key role in hearing. In addition, they are exploring potential therapies for CIB2-related hearing problems. In mice, they are using the gene editing tool CRISPR to modify dysfunctional CIB2 genes. They suspect that if this modification occurs in the first few weeks after birth, these mice, which are born deaf, will be able to hear. The scientists are also experimenting with gene therapy, using a harmless virus to deliver a copy of the normal CIB2 gene to baby mice that have the mutated version. Dr. Ahmed says the early results of these experiments are intriguing.

It is not clear how common CIB2 mutations are in the US population, or how large a role these mutations play in deafness in humans worldwide. In his research on a group of families in Pakistan that have a higher risk of deafness, Dr. Ahmed has found that about 8 to 9 percent seem to have mutations in CIB2. Overall, he says, the gene could play a role in tens of thousands of cases of deafness, and perhaps many more than that. He is also studying CIB2 among the general population. It may be that some versions of the gene also play a role in deafness caused by environmental conditions, creating a predisposition to hearing loss.

Arnaud Giese, PhD, a Post-Doctoral Fellow at UM SOM, and Yi-Quan Tang, PhD, from Cambridge University in England, are co-authors of this study. Other significant contributors include Dr. Riazuddin, William Schafer, PhD, from Cambridge University, Steve S.D. Brown, PhD, from the MRC Harwell Institute, UK, and Robert Fettiplace, PhD, from the University of Wisconsin.

“Hearing loss and deafness remain major physiological and sociological problems, with enormous economic and emotional costs,” said UM SOM Dean E. Albert Reece, MD, PhD, MBA, who is also the vice president for Medical Affairs, University of Maryland, and the John Z. and Akiko K. Bowers Distinguished Professor. “This innovative work by Dr. Ahmed and his colleagues opens a key molecular window that could lead to the development of cutting-edge translational treatments in the future.”

chemo patients get hearing loss 80% of time

IU cancer center researcher awarded $5.7 million to study chemo-induced hearing loss, toxicities

IU School of Medicine Sep 02, 2020

Lois Travis, MD, IU Simon Cancer Center, oncology

INDIANAPOLIS—A researcher at the Indiana University Melvin and Bren Simon Comprehensive Cancer Center has been awarded a five-year, $5.7 million National Cancer Institute grant to evaluate long-term health outcomes for cancer patients who receive platinum-based chemotherapies. 

An internationally recognized expert on cancer survivorship, Lois B. Travis, MD, ScD, leads the ongoing study that could lessen cancer treatment side effects for millions of patients. 

Nearly 6 million patients globally are diagnosed with a cancer each year in which first-line therapy potentially includes highly toxic, platinum-based chemotherapies. While the treatment may lead to hearing loss, ringing in the ears, numbness in hands and feet and other side effects, it is the only proven cure for the vast majority of testicular cancer patients. 

When IU’s Lawrence Einhorn, MD, developed a revolutionary therapy for testicular cancer in the 1970s, he flipped the 95 percent mortality rate for the disease to a 95 percent survival rate. His regimen of platinum-based cisplatin and two other drugs continues to be the standard care for testicular cancer. Einhorn is the Livestrong Foundation Professor of Oncology at IU School of Medicine and a physician scientist at the IU Simon Comprehensive Cancer Center.

Now Travis, Einhorn and a team of researchers from other top cancer centers are following more than 2,000 testicular cancer survivors who are part of the largest clinical cohort of germ cell cancer survivors worldwide. The alliance of researchers leads The Platinum Study, which was established through a previous NCI grant awarded to Travis in 2012. 

“We have shown with audiometric examination that 80 percent of the patients had hearing loss with one in five classified as severe to profound, levels at which hearing aids are recommended,” Travis, the Lawrence H. Einhorn Professor of Cancer Research at IU School of Medicine, said. Additionally, researchers found that 56 percent of patients had nerve damage called neuropathy and 40 percent had tinnitus or permanent ringing in their ears.

With this grant, researchers will tap into the existing cohort of patients who are part of the Platinum Study. The median age at diagnosis for testicular patients is 30, and the cohort’s median age now is 37. As patients age, researchers will continue to follow health changes, including if they are more susceptible to age-related hearing loss.

“We will examine the role of genetic variants in the platinum toxicities to try to identify high-risk subgroups,” Travis said.

The team of investigators wants to understand better which patients are at higher risk for these adverse outcomes and the daily effects of the toxicities. 

Collaborators of the Platinum Study gathered in Indianapolis in 2015.

“The goal is to follow this cohort for many decades to characterize the longitudinal trajectory of toxicities related to platinum-based chemotherapy,” she said. “For the first time, we will evaluate the impact and severity of the hearing loss and tinnitus on the patients’ physical, emotional and social functioning.”

Patients will complete questionnaires to track the different facets of their lives that are affected by hearing loss, or pain and numbness associated with neuropathy, as well as other toxicities. Researchers will also investigate the social and emotional consequences of the constant ringing in the ears, such as difficulty sleeping or concentrating.
Additionally, researchers will continue to analyze previously collected patient blood samples to track platinum levels, which can remain in the body for decades after chemotherapy is completed.

“Platinum is not completely excreted and is believed to be held in several body reservoirs. As tissue is remodeled with age, platinum regains access to the circulation,” Travis explained. “We will continue to measure the residual serum platinum levels.”

While cisplatin is used for many cancers, Travis notes that the testicular cancer patient cohort offers researchers a unique opportunity to study the toxicities.

“If we want to improve our understanding of long-term cisplatin-related toxicities, this is an ideal population,” she said. “When doing genetic studies, we know that all patients received about the same cumulative dose of cisplatin. We can then consider: who developed hearing loss and who didn’t, and what genetic and other factors are associated with this outcome?”

Ultimately, Travis hopes this research can determine which patients are most likely to experience adverse effects from cisplatin and then provide guidelines that could decrease damaging side effects, such as duration of treatments or improved symptom management.

“This is a critical part of my life’s mission: to decrease the cost of the cure for cancer survivors,” Travis said.

Collaborators include researchers from Memorial Sloan Kettering Cancer Center (Darren Feldman, MD), Dana-Farber Cancer Institute (Neil Martin, MD), University of Pennsylvania (David Vaughn, MD), University of South Florida (Robert Frisina, PhD), Vanderbilt University (Nancy Cox, PhD), University of Chicago (Eileen Dolan, PhD), Princess Margaret Hospital (Robert Hamilton, MD), the Royal Marsden Hospital (Robert Huddart, PhD), University of Rochester (Chunkit Fung, MD), Loyola University (Heather Wheeler, PhD), Harvard School of Public Health (Howard Sesso, ScD), and the British Columbia Cancer Agency (Christian Kollmannsberger, MD).

defective earplugs cause hearing loss mass suit

More than 200,000 people say that Combat Arms earplugs were knowingly defective, imperceptibly loosening and leaking in noise. By Mike Hughlett Star Tribune SEPTEMBER 19, 2020 — 8:22PM

RODRIGO ABD – ASSOCIATED PRESS FILEU.S. soldiers from the 2nd Brigade, 87th Infantry Regiment, 10th Mountain Division, in Helmand Province, southern Afghanistan, in June 2006. At the litigation’s heart is the U.S. Army’s request in 1999 to Aearo — before 3M owned it — to shorten the Combat Arms earplugs so they would fit in a carrying case and not interfere with helmet fit.TEXT SIZE15EMAILPRINTMORE

When 3M bought Aearo Technologies in 2008 it became a giant in the military earplug market. Aearo’s Combat Arms earplug was standard issue for U.S. soldiers in Iraq and Afghanistan.

A dozen years later, 3M is mired in one of the largest U.S. mass torts ever over the earplugs. More than 200,000 people — mostly veterans and active duty soldiers — say that Combat Arms earplugs were knowingly defective, imperceptibly loosening and leaking in noise.

Kevin Wilhelm, a Navy veteran, is one of them. Wilhelm said he now wears hearing aids almost constantly and is plagued by “nonstop” tinnitus — ringing in the ears, a common ailment among those suing 3M.

“I didn’t know these earplugs were defective,” he said. “I thought they were the best of the best.”

Indeed, the Combat Arms earplugs were groundbreaking, offering hearing protection while allowing soldiers to hear commands even in war zones.

3M maintains that the earplugs were not “defectively or negligently designed” and did not cause injuries. “Plaintiffs’ attorneys have created a false and baseless narrative regarding the product, and we will vigorously defend ourselves against such allegations,” 3M said in a statement.

Several “bellwether” earplug suits are scheduled for trial in April in a Pensacola, Fla., federal court. Their disposition is likely to set the tone for a possible settlement of all Combat Arms claims.

If the verdicts go against Maplewood-based 3M, the damages could tally in the hundreds of millions of dollars, if not more, based on the outcome of other large mass tort cases in recent years.

In July, a federal judge shot down a key 3M defense strategy, which would have granted the company some legal immunity as a government contractor.

At the litigation’s heart is the U.S. Army’s request in 1999 to Aearo — before 3M owned it — to shorten the plugs so they would fit in a standard-issue military carrying case. The company did so, but plaintiffs claim Aearo’s fix caused bigger problems.

Tests in 2000 at Aearo’s Indianapolis laboratory indicated that the shorter earplug didn’t always fit properly — and thus wasn’t always effective — unless it was inserted in a particular way, according to internal Aearo documents filed in court.

Two Aearo sales managers said in court depositions that soldiers did not need to know of the earplugs’ possible shortcomings.

Asked if it was “OK for Aearo/3M to conceal this information from the government,” former Aearo vice president Martin Salon said in a deposition: “I suppose it is, if the product is working — in most cases. … Nothing is perfect.”

3M said that neither it nor Aearo concealed information about the earplugs.

The earplug battle comes as 3M is grappling with an even bigger legal war over PFAS, a class of chemicals. Hundreds of cities, states and individuals are suing the company for allegedly contaminating water and soil with PFAS.

The earplugs in question are the second version of Combat Arms, which were sold to the government from 1999 to 2015 when 3M abruptly discontinued the product. The 200,000-plus earplug claims against 3M were lodged after the company settled a whistleblower suit in 2018.

That suit was brought by rival earplug maker Moldex-Metric on the federal government’s behalf, after an inquiry by the U.S. Army Criminal Investigations Command. The suit claimed Aearo knew about “dangerous design defects” in 2000.

In a 2018 report, the Army concluded that had the government known about tests Aearo had done in 2000 it may not have purchased Combat Arms earplugs. In the whistleblower settlement, 3M paid a $9.1 million penalty, but denied all claims and did not admit liability.

Auditory ailments are common occupational hazards in the military — and not only in combat. Hearing loss and tinnitus were the two most prevalent service-connected disabilities in 2019, according to the Veterans Benefits Administration.

Wilhelm, 57, said his tinnitus is so severe that he sleeps poorly and has developed anxiety and depression. The ringing “just grates and grates on you,” he said. “You never get a moment’s rest.”

Wilhelm, a Michigan native, retired in 2012 after 30 years in naval aviation, rising from jet mechanic to the top enlisted rank of maintenance master chief, often working on aircraft carriers.

He said he had worn ear protection throughout his career, switching to Combat Arms plugs by early 2003. Four years later, he said he began to noticeably struggle with his hearing.

The “dual-ended” Combat Arms earplug was considered an advancement.

The dark-colored end of the plug was solid, and when inserted into the ear would block steady noise, from helicopters to armored personal carriers. The yellow end was attached to a filter and when plugged into the ear, it would allow speech to be heard, while still blocking “impulse noise” such as gunfire.

The Combat Arms earplug became a big seller as the U.S. went to war in Afghanistan and Iraq. Aearo/3M tallied over $30 million in Combat Arms Version 2 sales from 1999 through 2009, mostly between 2004 and 2008, court records show.

The earplugs appeared to be quite profitable, too. In a deposition, one 3M marketing manager acknowledged that a set of earplugs cost 85 cents to make and were sold to the military for $7.63 apiece.

Plugs were tweaked

In 1997, Army and Aearo officials met for the first time to discuss a dual-ended earplug at an Army proving ground in Maryland. Doug Ohlin and Elliott Berger were both there.

Ohlin, an audiologist, was the hearing conservation manager at the Army’s Center for Health Promotion and Preventive Medicine. “Doug was the one that pretty much dictated how we were to provide hearing protection to the military,” one former Aearo and 3M sales executive said in a deposition.

Berger, an acoustical scientist, founded Aearo’s lab and had more than 20 years experience with the company when development began on the Combat Arms earplug. Well-regarded in hearing conservation circles, Berger worked for 3M until his retirement in 2018.

Ohlin said he chose the Combat Arms in 1999 because “it was the best game in town” — indeed one of the only games, court records show.

But the plugs turned out to be too long for the Army’s carrying case and could interfere with the fit of a soldier’s helmet. So, Ohlin told Aearo in 1999 to shorten them, and the first Combat Arm earplugs were shipped to the military that year.

In 2000, Berger supervised tests of the Combat Arms earplugs at Aearo’s lab, including one to establish a Noise Reduction Rating, or NRR. The higher an NRR, the better the noise protection, and an NRR must be derived from a test with 10 subjects.

The initial test was stopped after eight subjects because the results were variable and the estimated NRR was an 11, Berger and a colleague wrote in a July 2000 internal Aearo memo known as the “Flange Report.”

Other court documents said that an NRR of 11 is far below adequate, indicating the earplug would not stop sound as claimed.

A big part of the problem, Berger and his colleague found, was that because the plug had been shortened, it was difficult to fit deeply into some test subject’s ears, especially those with medium and larger ear canals, the Flange Report said.

For a second test, Aearo scientists changed the plugs’ fitting, pulling back the “flanges” of the yellow end sticking out of the ear. By folding the flanges, the plugs fit more consistently and deeper into the ear, the Flange Report said.

The second test achieved a Noise Reduction Rating of 22, much better than the first and in line with what was needed to sell the product.

Judge’s ruling pivotal

The Flange Report was never shared with the Army, wrote U.S. District Court Judge Casey Rodgers, who is presiding over the Combat Arms suits in Pensacola. Plaintiffs claim neither Aearo nor 3M even discussed the contents of the report with the military.

3M disputes that, saying in a statement that “the issues outlined in the Flange Report regarding fitting were communicated to the military,” and that the military was responsible for informing soldiers about the earplugs’ proper fit.

Berger, in a deposition, didn’t recollect providing test data to Ohlin. But he said this “entire development project was discussed with him and the issues from shortening [the earplug] to how it affected our testing were reviewed.”

Ohlin died in 2013. He had retired from his Army post in 2007, and soon thereafter became a contract consultant for Aearo and then 3M.

Veterans and soldiers suing 3M claim they were never told they needed to roll back the earplug’s flanges to receive proper hearing protection. “I would have adhered to that policy if I knew,” Wilhelm said.

The judge’s conclusions on the Flange Report were part of her July 24 order disallowing 3M’s use of the “government contractor defense” — a blow to the company’s legal plan.

That defense shields contractors from liability for defects in products designed and developed for the federal government. 3M has long said that the Combat Arms was designed in conjunction with the military.

However, Rodgers ruled that “the Army never issued a request for a design proposal for the new earplug.” And there was no contract between the Army and Aearo when Ohlin said the plugs needed to be shortened, she wrote.

“No reasonable jury could conclude that Dr. Ohlin or the Army made Aearo do anything,” the ruling said.

3M said it will continue to argue — and “ultimately prove” — that the company worked in close coordination with the U.S. military, and that the earplug’s design “reflected the direction and feedback of individuals acting on the military’s behalf.”

Bose Corp. introduces Sleepbuds II

Better Noise (tinnitus) Masking, New Relaxation Content, Now with Clinically Proven Technology

22 September 2020

Framingham, MA — Today, Bose announced Sleepbuds™ II, the next generation of its revolutionary bedtime wearable with technology now clinically proven to help people fall asleep faster. Sleepbuds II feature demonstrably better noise masking than their predecessor and introduce new categories of content to combat the other barrier to rest: the inability to relax. They combine a new acoustic and electronics design, a new enclosure that’s lighter than a dime, new proprietary ear tips for a secure, super-soft fit, and over 35 free tracks — all methodically produced and tested. The result is an engineering breakthrough: two tiny, ultra-comfortable, truly wireless buds that block, cover, and replace the audible distractions from loud partners, neighbors, dogs, and traffic — and reduce the mental distractions from long, busy days.

Sleep Buds Ii Wide

Bose Sleepbuds II will be available on October 6th for $249.95 and preorders start today. They aren’t active noise cancelling headphones or in-ear headphones with an added feature, and they don’t stream music or let you take and make calls — because every last detail was optimized for one thing — better sleep, all night, every night.

“Bose Sleepbuds II use advancements in our proprietary noise masking technology because covering sound — not cancelling it — is a better solution for sleeping,” said Steve Romine, head of the Bose Health Division. “You can’t duplicate the experience combining earbuds with apps, playing your music louder, or using earplugs and bedside machines — so millions of people are still suffering. We never gave up on helping them, and that’s why we’re so excited about Sleepbuds II. They ‘quiet’ more of the low frequencies found in the biggest threats to a peaceful bedroom — like snoring partners, idling engines, and nearby footsteps. And with new relaxation tracks, they help quiet your mind, too.”

The User Tested Study

In a first-of-its-kind study, Bose partnered with the University of Colorado Anschutz Medical Campus and the UCHealth CARE Innovation Center to test the impact of Bose sleep technology — which was clinically proven to help people fall asleep faster. The research also found that 100% of participants confirmed Bose noise masking worked against the common disturbances that kept them up or woke them up; 86% said the product helped them fall asleep easier; 76% said it helped them stay asleep; and 80% reported an overall improvement in sleep quality.

New Library of Content — Quiets the Room, Quiets the Mind

For control and updates, the free Bose Sleep App lets you set an alarm, change volume, and now includes three categories of content — all precisely developed, engineered, and mixed to overcome what keeps you up or wakes you up. When that’s caused by noise, 14 noise-masking tracks mirror the frequencies of night-time disruptions, hiding them under soothing layers of audio. When it’s caused by how you feel, new relaxation options are now available: 15 Naturescapes help calm racing thoughts with walks down a Country Road, Shore Line, Boardwalk, and beyond; 10 Tranquilities help lower stress and tension with tones to Lift, Drift, Dream, and more.

Better — from Noise Masking to Bud, Bluetooth to Battery, Transducer to Tip

Bose Sleepbuds II feature advancements in noise management, acoustics, psychoacoustics, and electronic miniaturization. Each bud is a just a quarter-inch deep — about the same as a pencil’s eraser — to dramatically reduce irritating contact when your head is resting on a pillow, even on your side. A new anti-friction coating covers each enclosure to prevent “squeaking” against fabric, and a new etched antenna produces a more reliable phone and tablet connection using low-energy Bluetooth. Inside, a new NiMH (Nickel-metal Hydride) battery powers 10 hours of run time, and a new miniscule circuit board stores up to 10 files from the Sleep App’s library. Its noise-masking tracks are matched to a new transducer to “cover and replace” more unwanted sounds than ever before — while a new pressure equalization design and soft silicone tips “block” more from entering your ear. With three sizes included, the tips are different than those made for daytime use. Their materials, shape, and design are all optimized to stay in place for a full night of peaceful, pain-free rest.

New Charging Case, Equally Compatible, IPX4 Rated

Sleepbuds II come with an improved anodized aluminum case that stabilizes each bud while they’re stored and charged and provides up to 30 additional hours of battery life. For convenience, they’re equally compatible with iOS and Android devices. For durability, they’re sweat- and water- resistant with an IPX4 rating.

Covid 19 causing hearing loss in some patients

Hearing LOSS symptoms Vary In COVID-19 Patients

Kevin Munro, PhD, a professor of audiology at the University of Manchester in the U.K., says that hearing loss and/or tinnitus tend to appear later in the course of a COVID-19 infection, or even after recovery. These symptoms can manifest in multiple variations and volumes, and more research needs to be done to pinpoint their exact prognosis. 

Munro, who also serves as the director of the Manchester Centre for Audiology and Deafness, is examining the link between COVID-19 and hearing loss in his own research.

“What surprises me the most is the number of people who are reporting problems with their hearing—I’ve been getting hundreds of emails from people telling me they’re experiencing hearing loss or tinnitus,” Munro says. “Still, I think we have to be careful and not say that COVID-19 is causing everyone to be deaf. We can say that more than one in 10 people are reporting that something has changed with their hearing, but we still don’t know everything about it.”

In his first study on the topic, Munro reviewed seven research projects studying hearing loss in COVID-19 patients. The patients all exhibited some form of hearing impairment: one patient had severe hearing loss in both ears, another mild hearing loss in one ear, and others experienced tinnitus that fluctuated between both ears. But there was no unifying root between them.

His second study examined 121 adult patients and found that 13% self-reported hearing deterioration or the development of tinnitus eight weeks after discharge.  

Munro says it’s too early to tell the extent of the damage COVID-19 will cause on the ears. Some of the patients contacting him have reported an increase in their symptoms, while others have noted improvement over time. 

What This Means For You

If COVID-19 has affected your hearing or triggered tinnitus, you’re not alone. Researchers don’t yet know if this condition is temporary or permanent, but they advise you to seek guidance from a medical professional as soon as possible. If the hearing loss is sudden, steroids may help reverse it in the first 24 hours.

SARS-CoV-2 Isn’t the First Virus to Cause Hearing Loss 

It isn’t rare for a virus to affect the auditory system. Even though MERS and SARS—two other coronaviruses from the same family as SARS-CoV-2—weren’t known to trigger hearing loss, other viruses can. 

Examples of these include:

  • Measles: Can cause an ear infection that leads to permanent hearing damage
  • MumpsTriggers severe swelling on one side of the face and usually inflicts hearing damage on the affected side
  • Human immunodeficiency virusCauses the body to attack its cells, sometimes leaving patients with hearing loss and tinnitus as a result 
  • Congenital cytomegalovirus infection: Can induce hearing loss in children

“We know that viruses can damage our hearing through different mechanisms that can cause permanent damage,” Munro says. “None of the other coronaviruses caused hearing problems, but none of the other coronaviruses cause the long-term health problems that we are now fighting with this particular one. That’s why people have been surprised when these young, healthy people who may have had mild symptoms are now reporting a hearing deterioration.”

How COVID-19 Could Affect the Ears

For Gaviria, her tinnitus most likely has a neurological root, as most of her post-COVID-19 symptoms—vertigo, concentration difficulties, and chronic brain fog—have neurological underpinnings. 

But scientists don’t yet know if these symptoms are purely neurological in origin or if they can also affect the auditory system in other ways.

Direct Auditory System Damage

Researchers at John Hopkins Hospital reviewed the autopsies of three patients who died of COVID-19 and found genetic traces of SARS-CoV-2 in the ears of two of them—showing that the virus can physically infiltrate the ears. 

However, according to Caitlin Barr, PhD, an audiologist and CEO of Soundfair Australia, it’s unlikely that the SARS-CoV-2 virus will enter your ear canal the way it would enter your mouth and nose.

“The organ of the ear that is responsible for taking in sounds is called the cochlea, and it’s made up of tiny auditory hair cells that can easily be damaged,” she tells Verywell. “The blood supply going to it is very small, so it’s very easy for a virus that’s in your bloodstream to go into your cochlea. Just a small amount can have a really big impact, and this is most commonly what causes the damage.” 

Nasal Inhalation

According to Munro, inhaling SARS-CoV-2 could trigger ear infection-like mechanisms that cause blockage in the ear.

Nerve Damage

Recent findings show that COVID-19 is sometimes associated with the development of Guillain–Barré Syndrome (GBS)—a rare condition that can lead to paralysis. Munro says that in this case, ears aren’t directly damaged, but the nerves that transmit sounds are. This type of damage is called peripheral neuropathy.

Cytokine Storm

Barr says that cytokine storm, a severe immune reaction released by the SARS-CoV-2 virus, can trigger inflammation throughout multiple organs in the body. If this inflammation occurs in any of the structures next to the ears, it could trigger a ringing sound. 

“The fact that these hearing symptoms have a later onset means it may take some time for the damage to build-up and be noticeable, and this could be because of a slow progression of inflammation to the brain, joints, or facial nerves,” Barr says. 

Medication May Contribute to Hearing Loss

According to Munro, COVID-19 is probably not the sole source of ear-related symptoms. Medications prescribed for the disease, like remdesivir, hydroxychloroquine, lopinavir, and ritonavir, are all ototoxic medications that cause damage to the cochlea.

“It’s possible that some of these patients were given high doses of drugs to help them with a life-threatening condition, and that it’s the drugs themselves that directly caused a hearing problem or tinnitus,” Munro says.

Munro is currently raising funds for a research study that looks at the longer-term impact of COVID-19 on adult hearing.

How to Cope With COVID-Induced Hearing loss and Tinnitus

Barr says she’s been inundated with calls since the start of the pandemic. She advises patients experiencing any form of hearing loss or tinnitus to initially consult with an audiologist for an evaluation. From there, the audiologist can perform a hearing test that measures ability to discern different pitches and frequencies. 

If the hearing loss is sudden, Barr says to seek medical attention immediately.

“[Steroids are] one of the medical interventions that could potentially reverse hearing damage,” she says. “But if it turns out to be permanent, there are therapeutic options available, such as hearing aids and cochlear implants.”

Tinnitus is more complicated. If it accompanies hearing loss, then treating the hearing loss will most likely treat the tinnitus, Barr says. However, if tinnitus happens on its own, then there is currently no medical remedy for it.

According to Barr, tinnitus can be triggered and aggravated by any form of stress. To combat mental stress, she recommends Cognitive Behavioral Therapy (CBT), which can reprogram the mind’s negative perception of the auditory symptoms and help people cope.

You can try CBT through apps such as Relax. This app also includes different sounds to buffer the tinnitus.

Bose Presents Sleepbuds II

Better Noise Masking, New Relaxation Content, Now with Clinically Proven Technology

22 September 2020

Framingham, MA — Today, Bose announced Sleepbuds™ II, the next generation of its revolutionary bedtime wearable with technology now clinically proven to help people fall asleep faster. Sleepbuds II feature demonstrably better noise masking than their predecessor and introduce new categories of content to combat the other barrier to rest: the inability to relax. They combine a new acoustic and electronics design, a new enclosure that’s lighter than a dime, new proprietary ear tips for a secure, super-soft fit, and over 35 free tracks — all methodically produced and tested. The result is an engineering breakthrough: two tiny, ultra-comfortable, truly wireless buds that block, cover, and replace the audible distractions from loud partners, neighbors, dogs, and traffic — and reduce the mental distractions from long, busy days.

why wear 2 hearing aids

.

If you have a hearing loss in both ears it is very important to wear 2 hearing aids.

A few reasons why:

1) Better understanding of speech, especially in noise:
Research shows that people who wear two hearing aids understand conversations and speech significantly better than those who wear only one.

2) Better ability to tell where sound is coming from:
This is called localization, and it helps you determine where traffic is coming from or which person is speaking in a group.

3) Better sound quality:
When you listen to a stereo system you get great sound. Wearing two hearing aids gives you similar results and increases your hearing range from 180 degrees to a full 360 degrees.

4) Makes hearing less tiring and listening more pleasant:
You won’t have to strain to hear with your ‘good’ ear, making life much more relaxing.

5) Keeps both ears (full brain) active which can help reduce further hearing loss:
Research Studies show that if you don’t use your hearing, you can lose it. By only wearing one hearing aid, you can cause further damage to the other ear (brain area). The use of two hearing aids helps eliminate this problem.

If you have hearing loss in both ears, but you’re trying to get by with just one hearing aid (or, none at all), you’re doing yourself a great disservice.

hearing aid & face mask problems solved

First FDA-Registered UV-Sterilizing Clear MaskLEAF “smart mask” has reached almost $4 Million in backing on Indiegogo. Delivery is expected in the coming weeks. This mask is TOTALLY CLEAR.
https://www.indiegogo.com/projects/leaf-mask-world-s-first-fda-uv-c-n99-clear-mask#/

Those who wear behind-the-ear hearing aids encounter some problems wearing a standard face mask with elastic ear loops.

The ear loops may press on the hearing aid tubing that connects the hearing aid to your ear. It can get on top of, or underneath the hearing aid and press against the ear, causing pain or discomfort. You may also pull the hearing aid off the ear when removing your face mask.

A better solution is a mask like my mask where the loops go around the back of the head, instead of over the ears. See photo above .

Additional security against dropping your hearing aids is a custom DIY earmold. WHAT ARE EAR MOLDS FOR HEARING AIDS?


 

Covid 19 face masks make it hard to hear

Hearing Loss and face Masks are a difficult combination.

The mask physically blocks the speech sounds.

According to a medical study highlighted in Hearing Review, medical masks act as a low-pass acoustic filter for speech, weakening the high frequencies spoken by the wearer by up to 12 dB depending on the type of mask. The study concludes, “The speech quality degradation, in combination with room noise/reverberation and the absence of visual cues, renders speech close to unintelligible for many patients with hearing loss.”

Lipreading cues are absent.

Like many people with hearing loss, I am usually speechreading while I listen. The lipreading cues help me better understand speech, while the facial expressions help me to find the emotion behind the words. With a mask, neither of these clues are available making it more taxing to organize the sounds into a meaningful word or phrase. This can lead to hearing loss exhaustion from the increased listening effort.

The 6-feet apart rule compounds the issue.

Along with wearing masks, people have been asked to physically distance from one another by staying home as much as possible and by maintaining a six foot distance from others when in public spaces. This rules helps reduce the likelihood of transmitting the virus from one person to another, but it also makes it more difficult to hear since most hearing devices work best when they are within six feet of the source of the sound.

Tips For Communicating With People Wearing Masks

When you talk to someone with a face mask most people have difficulty understanding each other. Now, add a hearing loss and it may become impossible to understand.

With a hearing loss, understanding speech does not come naturally. It takes effort. The clues we get from lip movements and facial expressions are almost as important as the sounds that are amplified by our hearing Aids. We must look as well as listen in order to fully understand. Masks, while necessary and important for public health, make this process much more challenging.

Supplement with speech-to-text apps

If you have a speech-to-text apps like Live Transcribe (Android only) You can hold your phone as close to the person as possible while maintaining physical distance. The closer the microphone is to the person speaking, the better chance it will have to pick up the sound. Practice at home so you are not fumbling with the app in real time.

Use paper and pen if necessary

You can use them to prepare signs in advance with your name and what you need to say. For example, if you are picking something up at the pharmacy, include your name, what you are picking up, and that you have trouble hearing so they know to communicate with you carefully.

You can also use your phone as a notepad

deafness cured in new experiment

A new form of genetic editing cured deafness in a new successful trial…

The Broad Institute of MIT and Harvard. A team of researchers has used a technique called base editing to cure deafness in mice.

The Broad Institute previously was instrumental in developing CRISPR genetic editing technology. CRISPR corrects genetic mutations by using an enzyme to cut out an unwanted genetic mutation and replacing it with healthy DNA.

Base Editing is different in that it doesn’t cut the DNA. Instead, it can “rewrite” the actual letters in the DNA sequence.

DNA is the building block of life. It is the hereditary material contained in every cell of our body.

All strands of DNA consist of a sugar, a phosphate group, and a base pair. The sugar and phosphate group are identical in every strand of a person’s DNA. They are the “backbone.” The base pair determines what genetic information is expressed.

In DNA, there are only four bases that make up a pair. They are adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine always bonds with thymine to form a pair. And guanine always bonds with cytosine to form a pair.

The only naturally occurring base pairs in DNA are A-T and G-C. When we talk about “letters,” this is what we are talking about. Below is a visual:

DNA Base Pairs

Source: How Stuff Works

Now, Genetic Mutations occur when one of these bases is transcribed incorrectly – that is, when the letters don’t match up properly.

Base editing technology corrects these mutations by “rewriting” the letters so that they match up correctly. In other words, base editing can change any single letter to any other.

When it comes to a certain kind of deafness in mice, the condition is caused by a single mutation. That makes it relatively easy to cure with base editing.

Using base editing, the team proved that the mice could hear sounds as quiet as 60 decibels, which is the level of a normal conversation. That’s not 100% hearing, but it is still a remarkable achievement. The mice could hear again.

This technique could easily be applied to humans. That’s the next step for the team at Broad.

Well, base editing is an exciting technology that’s on the rise. Base editing is now where CRISPR was six or seven years ago. It is not a matter of being better or worse than CRISPR. This is another tool to help cure all human disease.

We’re finding that with some genetic mutations, different enzymes work better than others. The same will likely be true about using base editing versus CRISPR depending on the situation.

We will see some exciting developments in base editing technology in the last half of this year. This is another powerful tool when it comes to eradicating all human disease.

Why hearing aids can cause itchy sore ears.

What can you do when the hearing Aid is making your ears itch?

Answer

There are many possible causes, that the medical books list.

The ear canal has very thin delicate skin; that even hair, ear wax, allergies bacteria, etc. may cause itching in the ear.  When you add a hearing aid, it can add other causes. I have been wearing hearing aids since 1956. Before I discus my experience, let us examine the usual factors.

Open Fitting hearing aids

The domes/tips for OPEN FITTINGS are made from medical grade silicone rubber. So allergic reaction is less likely than for a custom earmold made by a factory/Lab However, some people may be allergic to the cleaning agent used to clean the dome/tube tip.

One of the most common causes of itching for OPEN FITTING AIDS is poor fit of the dome in the ear canal. Whether it is a thin tube or receiver (speaker)-in-the-ear canal (RIC,RIE) style, we are dealing with non-customized fitting and limited (not perfect) tube/receiver lengths and dome sizes to select from. When people complain about itching/ irritation with an open fitting, see if the tube too short, pulling the skin of ear too tight, or is it too long, causing the hearing aid to “lie” above the ear canal? A too short tube will cause pressure on the skin; a too loose tube may cause the hearing aid to move easily and cause irritation when the head is moved, talking or chewing. Is the dome size right?

There is no perfect Dome size, because the ear canal is irregular, oval,and NOT ROUND like the Domes.. Trying to change the dome size or change to a different type of dome (open dome, tulip dome or closed dome) are the usual attempts to solve the problems.

If the physical fit is as good as can be achieved, but the person still complains about irritation, applying a bit of lubricant (such as Olive oil) on the dome may help. Finally, a customized earmold can also solve issues with itching, especially if the itching is caused by the dome not remaining in a fixed position in the ear canal, but keeps moving with smiling, chewing and talking.

Closed Dome/ earmolds

For closed fittings with custom earmolds/shells, itching or irritation can be due to poor fit, allergy to the plastic materials, moisture in the ear or a wax accumulation. Poor fit is also a common cause of itching. Allergy to earmold materials is less common than fit issues but it does happen, especially for earmolds made from Laboratory acrylic or epoxy resin. have been reported to cause contact dermatitis in the ear It can be helpful to keep hearing aids cleaned and put in a hearing aid dryer during the night.

Dry skin tends to peel or crack and is extremely sensitive to irritation; scratching will further damage the skin and make the itching worse. Alcohol should not be used to clean the ear if the skin is dry as this will make matters worse. A few drops of olive oil may help keep the ear from getting too dry and also protect it from water and bacteria. However, do not put much oil in the ear if the person wears RIC/RIE or custom in ear aids as this may cause damage to the receiver (speaker).

Summary

Itching due to wearing hearing aids is common, but it can be treated or eliminated. Make sure you get the best fit; keep both ears and hearing aids clean and dry; use lubricant or moisturizer if needed, switch to non-allergenic material (silicone rubber) if an allergic reaction occurs, and refer to an ENT or dermatologist if necessary. Using HCPB DIY Medical Grade silicone rubber earmolds solves these problems.

I spent the first 8 years of using hearing aids by using Custom Lab Lucite earmolds. I had issues with soreness, itching and poor hearing quality. Then I developed my HCPB medical grade silicone rubber earmolds. Thy solved all my problems and then offered them to my patients, in my hearing aid practice. Now they are available to anyone at this website at factory direct lowest price.

Coronavirus focus’ interest in clear-window FACE masks

Coronavirus Puts Spotlight on Clear-Window Surgical Masks

WRITTEN BY

David Copithorne

Content Director

MAY, 2020

Last year, when I accompanied my wife to a series of visits to City of Hope Hospital in Southern California, I was stymied by health care workers and other patients wearing surgical masks. Traditional surgical masks not only muffle speech; they make lipreading completely impossible. As someone with severe hearing loss, I could never be sure of what the professionals were saying, and asking for constant repeats increased my anxiety. Communicating with patients was an even bigger challenge, because I didn’t want to invade their personal space by leaning in to hear better.

Accessible Mask Blurred

The Communicator™ Clear Window Surgical Mask eliminates lipreading problems while providing FDA-approved ASTM Level 1 protection.

Sadly, I wondered why no one had come up with a see-through surgical mask to enable lipreading. But then a quick Google search revealed that someone already had. Our resulting story about Dr. Anne McIntosh and her Safe’N’Clear Communicator™ Clear Window Surgical Mask hit a nerve. The story went viral, and thousands of people (from doctors and nurses to everyday people) expressed an urgent need for the solution.

In addition to explaining the speech-reading benefits of a transparent surgical mask, Dr. McIntosh was also forthcoming about the challenges the medical industry faces in providing enough surgical masks to those who need them. Her masks are made in America, where manufacturers are faced with a huge backlog of orders for all kinds of surgical masks. Manufacturers have already complained about the lack of foresight by the government and large customers who failed to stockpile more of them.

Coronavirus renews interest in clear-window masks

With Coronavirus, more people are wearing surgical masks than ever. In fact, even while experts have debated the effectiveness of the masks, rapid growth in demand has led to a global supply shortage. As more and more people put on the masks, more and more faces are hidden to those—like myself—who rely on lipreading to communicate. That’s why it’s time to take another look at an obvious solution that should get far more attention: clear-window surgical masks.

Katharine Bouton, an influential hearing-loss-advice author, published a short post pointing to efforts of another company (ClearMask) to come up with a clear-window surgical mask for professionals and patients. Among other things, she is recommending that the Hearing Loss Association of America (HLAA) start advocating for their use. She also posted an extremely helpful longer article on Coronavirus and People with Hearing Loss.

Active Noise Cancellation

Active Noise Cancellation on AirPods Pro uses two microphones combined with advanced software to continuously adapt to each individual ear and headphone fit. This removes background noise to provide a uniquely customized, superior noise-canceling experience that allows a user to focus on what they’re listening to — whether it’s a favorite song or a phone conversation.The first microphone is outward-facing and detects external sound to analyze environmental noise. AirPods Pro then create an equivalent anti-noise that cancels out background noise before it reaches the listener’s ear. A second inward-facing microphone listens toward the ear, and AirPods Pro cancel remaining noise detected by the microphone. Noise cancellation continuously adapts the sound signal 200 times per second.

Immersive Sound

AirPods Pro deliver superior sound quality with Adaptive EQ, which automatically tunes the low- and mid-frequencies of the music to the shape of an individual’s ear — resulting in a rich, immersive listening experience. A custom high dynamic range amplifier produces pure, incredibly clear sound while also extending battery life, and powers a custom high-excursion, low-distortion speaker driver designed to optimize audio quality and remove background noise. The driver provides consistent, rich bass down to 20Hz and detailed mid- and high-frequency audio.

Transparency Mode

Transparency mode provides users with the option to simultaneously listen to music while still hearing the environment around them, whether that’s to hear traffic while out for a run or an important train announcement during the morning commute. Using the pressure-equalizing vent system and advanced software that leaves just the right amount of noise cancellation active, Transparency mode ensures that a user’s own voice sounds natural while audio continues to play perfectly.Switching between Active Noise Cancellation and Transparency modes is simple and can be done directly on AirPods Pro using a new, innovative force sensor on the stem. The force sensor also makes it easy to play, pause or skip tracks, and answer or hang up phone calls. Users can also press on the volume slider in Control Center on iPhone and iPad to control settings, or on Apple Watch by tapping on the AirPlay icon while music is playing.

Performance and Battery Life 

The size and performance of AirPods Pro are made possible by a revolutionary system-in-package (SiP) design with the Apple-designed H1 chip at its core. The H1 features 10 audio cores and powers everything from sound to Siri. The extremely low audio processing latency of H1 enables real-time noise cancellation, delivers high-quality sound using adaptive technology and responds to hands-free “Hey Siri” requests — all at once.AirPods Pro feature the same great battery life as AirPods with up to five hours of listening time. In Active Noise Cancellation mode, AirPods Pro deliver up to four and a half hours of listening time and up to three and a half hours of talk time on a single charge. Through additional charges from the Wireless Charging Case, AirPods Pro deliver over 24 hours of listening time or over 18 hours of talk time.2 Charging is as simple as placing the AirPods case on a Qi-certified charging mat or using the Lightning port while on the go.

Additional Features

  • The Ear Tip Fit Test helps ensure users get the best audio experience from AirPods Pro by testing the quality of the seal and identifying the best ear tip size for them. After placing AirPods Pro in each ear, advanced algorithms work together with the microphones in each AirPod to measure the sound level in the ear and compare it to what is coming from the speaker driver. In just seconds, the algorithm detects whether the ear tip is the right size and has a good fit, or should be adjusted to create a better seal.
  • Voice-activated Siri uses the H1 chip to enable hands-free “Hey Siri” to play a song, increase the volume, make a call or get directions. 
  • Audio Sharing makes it easy to listen to the same song or watch the same movie with a friend by simply bringing a second pair of AirPods close to iPhone or iPad.3

Chocolate can reduce hearing loss, study reported

A team of researchers in Korea conducted a rigorous nationwide study of the chocolate consumption of 3,575 subjects—between 40 and 64 years old—and the results were startling: Hearing loss was significantly lower for those who regularly consumed chocolate:

The rate of any hearing loss (unilateral or bilateral) in the subjects who consumed chocolate (26.78% (338/1262)) was significantly lower than that in those who did not (35.97% (832/2313)) (p < 0.001). Chocolate consumption was independently associated with low odds of any hearing loss (adjusted odds ratio = 0.83, 95% confidence interval = 0.70 to 0.98, p = 0.03).

Korean National Health and Nutrition Examination Survey

The researchers concluded that “the severity of hearing loss was inversely correlated with the frequency of chocolate consumption.” In other words, the more often you eat chocolate, the better your odds of avoiding severe hearing loss.

A national nutritional/medical survey

The study used data from the Korean National Health and Nutrition Examination Survey (KNHANES), which records the health and nutritional status of Koreans. Respondents were given hearing threshold tests to determine the presence and degree of sensorineural hearing loss.

To control for other pathologies that may have contributed to hearing loss, the researchers performed rigorous physical examinations on each subject. Subjects also provided detailed information on their consumption of chocolate and other foods. Information on the frequency and quantity of food consumption summarizing the subjects’ previous year of eating was collected by trained dietitians.

The research did not identify exactly how or why chocolate prevents hearing loss. However, researchers said the size of the sample and rigor of their analysis gave them the confidence to come to a strong conclusion: “Our results suggest that chocolate plays an oto-protective role against hearing loss.”

Cocoa may be key to preventing hearing loss

Cocoa is known to be an anti-oxidant that can help prevent cardiovascular inflammation. The researchers hypothesized that the same effects could reduce vascular hypertension in the ear, a condition that is associated with hearing loss. While this causative link was not definitive, the researchers did note a high correlation between chocolate consumption and reduced vascular hypertension:

Those who did not consume chocolate had higher risks of hypertension and dyslipidemia than did those who consumed chocolate. Chocolate exerts antioxidant and anti-inflammatory effects and has been shown to have therapeutic benefits for patients with cardiovascular diseases. Specifically, cocoa, a major ingredient of chocolate, attenuates vascular risks by reducing blood pressure and improving endothelium-dependent vasodilation. In line with this, several investigations demonstrated the causal relationship between vascular risk factors and hearing loss. Thus, our results suggest that chocolate decreases the rates of hypertension and dyslipidemia, which enables the preservation of hearing.

Korean National Health and Nutrition Examination Survey

Unfortunately, other beloved foods don’t appear to have the same preventative properties. Specifically, the researchers l looked into the consumption of ice cream, cake, and cookies. The data indicated that these foods had no impact, positively or negatively, on rates of hearing loss: “there was no association between hearing loss and the consumption of sweet products without cocoa.”

Chocolate doesn’t help relieve tinnitus

The researchers also investigated the relationship between chocolate consumption and tinnitus, the annoying ringing, buzzing, humming and other sounds that many people have in their ears.

Because many people who have hearing loss also have tinnitus, the team hypothesized that chocolate consumption might also help prevent tinnitus, but it didn’t.

Earmold Dome slipping in ear?

If your Dome (eartip) slips in or out of your ear, you are not alone. It is a common problem and it is no wonder. The Domes are round but your ear csnal is irregular and more oval shaped.

The solution is easily and inexpensively solved. Instead of using a tight-fit dome, use a slightly smaller size (preferably OPEN FIT), for comfort. Then mix a small portion of HCPB Medical Grade silicone putty and add it to the dome and tube before inserting it in the ear

The new cstom fit earmold that you made in just 3 minutes will now comfortably lock it in the ear and a side effect will be improved hearing. There will no longer be any dome slippage in the ear and it will prevent the hearing aid from falling off the ear. This will also prevent the dome tip from coming off the tube and staying in the ear, if you have used an Open (not closed ) dome.
