The structure of the hearing aid
Since the electronic hearing aids were put into use in the early 20th century, the structure of the hearing aids has not changed much, and it is still composed of a microphone, an amplifier, a receiver and a power supply. But hearing aid parts are shrinking in size, sound quality is improving, and there's more selective control.
1 Microphone: collects sound and converts it into radio waves.
2 Amplifier: Increase the intensity of the radio waves.
3 Receiver: Just the opposite of the microphone, converts the increased electrical energy back into sound waves.
4 Power: Small battery.
5 Shell: Protects the internal structure.
