Digital hearing aids, Batteries, and best.

Hello and welcome to Digital Hearing Aids Depot.com. We are a website designed to bring you the latest news and information about digital hearing aids and other hearing helping products.

A hearing aid is an apparatus which typically fits in or behind the wearer's ear, and is designed to amplify and modulate sounds for the wearer. There are many types of hearing aids, which vary in size, power and circuitry.

Every electronic hearing aid has at minimum a microphone, a loudspeaker (commonly called a receiver), a battery, and electronic circuitry. The electronic circuitry varies among devices, even if they are the same style. The circuitry falls into three categories based on the type of audio processing and the type of control circuitry.

Both the audio circuit and the additional control circuits are fully digital. The hearing professional programs the hearing aid with an external computer temporarily connected to the device and can adjust all processing characteristics on an individual basis.

Fully digital circuitry allows implementation of many additional features not possible with analog circuitry and can be used in all styles of hearing aids and is the most flexible. Fully digital hearing aids can be programmed with multiple programs that can be invoked by the wearer, or that operate automatically and adaptively.

These programs reduce acoustic feedback or whistling, reduce background noise, detect and automatically accommodate different listening environments like loud vs. soft, speech vs. music, and quiet vs. noisy.

They also control additional components such as multiple microphones to improve spatial hearing, transpose frequencies which is shifting high frequencies that a wearer may not hear to lower frequency regions where hearing may be better, and implement many other features.

 Fully digital circuitry also allows control over wireless transmission capability for both the audio and the control circuitry.
Control signals in a hearing aid on one ear can be sent wirelessly to the control circuitry in the hearing aid on the opposite ear to ensure that the audio in both ears is either matched directly or that the audio contains intentional differences that mimic the differences in normal binaural hearing to preserve spatial hearing ability.

Audio signals can be sent wirelessly to and from external devices through a separate module, often a small device worn like a pendant and commonly called a streamer that allows wireless connection to yet other external devices. This capability allows optimal use of mobile telephones, personal music players, remote microphones and other devices.
With the addition of speech recognition and internet capability in the mobile phone, the wearer has optimal communication ability in many more situations than with hearing aids alone.

This growing list includes voice activated dialing, voice activated software applications either on the phone or on the internet, receipt of audio signals from databases on the phone or on internet, or audio signals from television sets or from global positioning systems.
