How Hearing Devices work?

What is a hearing device?

A hearing aid is an electroacoustic device that is designed for sound modulation and amplification. This battery powered device consists of:

  • Microphone
  • Amplifier
  • Receiver

Microphone detects sounds in the surroundings and converts them into electronic signals and then sends to the amplifier. Some hearing devices have 2 microphones to help distinguish background noises. Amplifier's role is to amply the sound and make it louder. Receiver's job is to carry the conversion to the inner drum of the ear which allows you to hear sounds, conversation, music etc.

The Circuit:-

The Circuit is the backbone of a hearing device. It deciphers the sound and deals with the transformation of the incoming sound. Since it is programmed with a software, the circuit is smart enough to know which sound should be amplified and which sound should be reduced. For example: unnecessary noises on a highway are softened to better the audibility. It also softens noises in the background and amplifies sounds that you struggled to hear without a hearing device.

Hearing aid programming:-

Hearing aid is programmed by a specialist called 'Audiologist'. An audiologist programs the hearing aid to amply certain sounds and reduce the others depending upon the type of the hearing loss of the patient.

Battery:-

Battery is an indispensable part of a hearing device as the device cannot work without power. It is better to keep 2 batteries with you, so that you are not left to your own devices when one drains out completely.
