All hearing aids use similar parts to carry sounds from the environment into your ear and make them louder. Over the past ten years the hearing aid industry has reduced the size of hearing aids to near invisibility. Hearing Resources works with several manufacturers so that we have plenty of choices to help find the right product for you. Acoustic feedback (whistling from the hearing aid) can be annoying, embarrassing, and in some cases, prevent the hearing aid wearer from using the correct amount of gain. With digital hearing aids, it is possible for the hearing aid to analyze an incoming signal and differentiate speech from a noise signal. Using special microphones or phase cancellation signal processing, it is possible to configure a hearing aid so that sounds from the side, and especially the back of the hearing aid user are amplified less than sounds originating from the front.
With this special circuit, electromagnetic signals can be picked up from the handset of the telephone and amplified in a manner similar to the amplifying function of the hearing aid. Hearing aids vary a great deal in price, size, special features and the way they’re placed in your ear.
Hearing aid designers keep making smaller hearing aids to meet the demand for a hearing aid that is not very noticeable. The ENT Center and Hearing Resources are able to work together to provide complete medical, surgical or amplification needs.


Many of today's hearing aids have an automatic feature that quickly detects acoustic feedback and cancels it. This has changed rapidly the past few years, and today, nearly all hearing aids sold in the U.S. Some people are concerned with cosmetics and prefer the least noticeable hearing aids, in the way that you might choose contact lenses instead of framed eyeglasses. They can also more accurately mimic the way you used to hear before you experienced hearing loss. Each level offers digital hearing solutions based on your level of hearing loss, lifestyle and budget. The remote that came with my hearing aids has been great in helping me in restaurants and other crowded or noisy places. The AGC also allows for most individuals to not worry about adjusting the volume on the hearing aid as the hearing aid will automatically adjust volumes in different environments, similar to a normal hearing ear. Note, however, that what a typical hearing aid user might consider to be"noise," (background talkers at a party) might not be considered "noise" by the hearing aid.
Directional technology is available on all hearing aid styles except CICs (because of size constraints). One advantage of multiple channels is that features such as gain and compression can be programmed differently to reflect changes in the patient's hearing across frequencies.


Then it analyzes and adjusts the sound based on your hearing loss, listening needs and the level of the sounds around you. The problem is that the smallest hearing aid may not be the most suitable hearing solution for you for a variety of reasons.
Although feedback can be managed it can never be eliminated completely no matter the hearing aid. Your specific hearing loss may require more power than available in CICs, you might not have the manual dexterity to manipulate them, or your ear canals may not allow them to be retained in your ears. Research has shown that many hearing aid users prefer directional technology for listening in noise. In these instruments, the Telecoil can be accessed through a push button on the hearing aid or by the use of a remote control.
