Hearing aid devices work by magnifying the sound that is transmitted from your surroundings to your inner ear to improve your hearing capabilities. The majority of hearing aid manufacturers are eliminating the production of the old analog hearing aids. They have been replaced by digital hearing equipment.
According to the Healthy Hearing website, nearly all hearing aids sold in 2008 (97 percent) were digital, based on statistics compiled by the Hearing Industries Association (HIA).
Digital hearing devices provide the hearing impaired with clearer and cleaner audio that is comparable to how digital television has improved video images.
According to the American Speech-Language-Hearing Association, there are at least 20 manufacturers of digital hearing aids that are sold under more than three dozen different model names. The digital processing of hearing aids involves the intricate management of signals. The technology consists of the use of a computer chip that translates external sound into digital code that can be evaluated and fine-tuned for each wearer. The signals are then transferred back into sound waves and transported to your ears.
Digital hearing aids can accommodate the varying needs of distinctive hearing loss patterns. They have the capability of separating sound into several frequency zones and amplifying each one based on individual hearing loss. Audio levels can be tuned to low, medium and high sounds. This feature prevents the overmodulation of loud noises.
Digital hearing aids provide overall listening comfort by splitting background noise apart from an intended audio signal, such as someone who is speaking to you.
The directional microphone feature can help you hold a conversation in a noisy setting by permitting sound coming from a certain direction to receive greater amplification than sound from other directions.
Digital hearing aids can also identify and mute whistling noises. Its feedback separation capability restrains screech noises that can occur when the device gets too close to a phone.
