Working principle
All hearing aids use the same basic components to channel ambient sound into your ears and amplify the sound. Most hearing aids are electronic, and all are powered by conventional hearing aid batteries or rechargeable batteries.
A small microphone is used to pick up the sounds in your environment. A computer chip with an amplifier converts the incoming sound into a digital code. The chip adjusts the sound based on your hearing loss, your listening needs, and an analysis of the sound levels around you. The amplified signal is then converted back into sound waves and sent to your ears through a speaker (sometimes called a receiver).
components
The basic structure of in-the-ear hearing aids is basically the same as that of in-the-canal hearing aids, which are composed of a shell, microphone, integrated circuit amplifier, potentiometer, receiver, etc. The shell of in-the-ear hearing aids is the same as that of in-the-canal hearing aids, which are customized according to the shape and size of the patient's ear canal (in-the-ear hearing aids also include the concha cavity), and the hearing aid movement is installed in the shell.
