Background noise is undesired noise that competes with some thing or someone that you want to hear.
You know that if you get close to the sound source and face it, you will hear better. Cupping your hand behind your ear helps, also. You can ask the person to speak louder. But some times the noise is just too loud and overcomes what you want to hear.
If the sound you want to hear is a TV or other remote sound source, you can turn up the volume, unless it annoys others in the room. Another solution is to get a wired or wireless device with independent control that is connected to your hearing aid or independent speakers that are in or close to your ears.
Hearing aid manufacturers began providing a solution to this problem in 1958 when Maico Hearing Aid Co. introduced behind ear hearing aids with a DIRECTIONAL MICROPHONE It was actually 2 microphones, in one hearing aid. The one facing forward was amplified more that the rear facing microphone. So the direction that you faced was always louder than the sounds coming from behind. Today, they are still optionally available and with a variety of Directional reception patterns.
There are many new advances to provide improved hearing aid use in noise, such as: LAYERED NOISE REDUCTION , that reduces noise when speech is not present, WDRC wide range compression, selectable time constant modes, “Look-ahead Detection” to reduce loud impulse noises, built-in programmable choices for different noisy environments, T Coil for noiseless phone use, Etc.
All of these methods are very helpful, except if the ear canal is not sealed by an ear mold, the outside sounds can leak in to the ear drum and compete with the desired amplified sound. That is why the best hearing aid can fail in a noisy environment, unless it has a well-fitted custom ear mold. Many studies have been done that demonstrates this problem and it’s ear mold solution, to keep uncontrolled noise out of the ear. They work just as you make ear plugs to keep out unwanted noise when sleeping, flying, shooting, etc.
Now, you (THE PUBLIC) or some professional hearing aid dispensers can make a 10 minute comfortable, inconspicuous, custom ear mold by using our DIY ear mold material. It can be modified to suit each individual hearing loss. They are available in several different skin colors and all at a VERY LOW COST. See the MENU for ear mold kits on this site for different types of hearing aids.
