Modern features to Hearing Instruments

Most hearing instruments today have many features to improve the quality of life like;

Whistling from the hearing instrument is annoying, embarrassing, and in some cases, prevent the patient to live comfortably. Adaptive Feedback Cancellation is a technology designed to manage the transitory feedback getting rid of whistling from the hearing instrument.

Loud sounds: Automatic Gain Control – Output is a technology designed to put a ceiling on loud sounds, adjusted to correspond the patient threshold of discomfort, maintaining sounds below this level.

Low sounds: Automatic Gain Control – input “repackages” the speech signal received (or other incoming sounds) to correspond your level of hearing. This means that if the incoming sound has a 30 dB loudness range, and you can only hear at a 60 dB level, the Automatic Gain Control – Output system will adjust the incoming sound to fit your level. This reduces dependence on the volume control.

Noise: Digital hearing instruments can analyze incoming signals and differentiate speech from a broad-band noise signal – Digital Noise Reduction. If the dominant signal is believed to be noise there will be a reduction in volume. Note, however, that what you might consider noise.

Sounds from behind and from the side of the patient will be amplified less than sounds originating from the front. This technology is called Directional Microphone Technology and is available in all hearing instruments.
