How does a hearing aid work?
A hearing aid is an electronic device with a small microphone that amplifies weak sounds through a small speaker. You must have some ability to hear for the device to work. And because hearing loss affects people in different ways, you need to get the right device for you. Dr. Sinha offers several types of aids to fit your needs and budget. We offer the latest, most advanced digital programmable aids that use modern computerized digital signal processing to enhance your hearing in a wide variety of sound situations. These also include “invisible” hearing aids, that is, hearing aids that fit completely within the ear canal so they are not seen even when someone is looking directly at your ear!
A hearing aid is like a miniature PA (public address) system designed for personal use. It is designed to take in an acoustic signal of low intensity and retransmit it at higher intensity so that it may be better heard. The hearing aid microphone receives ambient sound and sends it to the amplifier, which conditions the sound to make it louder. The receiver mechanism sends the amplified sound into the ear canal. The volume control, typically outside the aid, adjusts the loudness of the amplifer. The hearing aid battery supplies the power to make the device work.
