How a Hearing Aid Works
In its simplest form, a hearing aid is an amplifier that makes sound louder. Today’s hearing aids do much more than that, but they wouldn’t help much if they didn’t amplify. Let’s take a look at basic elements that make amplification possible.
A microphone converts sound into an electrical digital signal.
An amplifier increases the strength of that signal.
A speaker/receiver converts the amplified signal back into sound and sends it to the inner ear. The brain “hears” and understands the sounds.
Hearing aids require power to amplify sound. An inexpensive and convenient source is a battery. Hearing aid batteries come in five sizes, which are based on the style and size of the hearing aid.
Of course, hearing aids do much more than just amplify sound. They also improve hearing in difficult situations with advanced technology features like feedback elimination and the ability to hear better on the phone. Wireless hearing aids also allow you to wirelessly connect to your favorite devices like TVs, music, phones and more
