What are the different components of a hearing aid?


Hearing aid components include: a microphone that can change the acoustic input to an electrical signal, an amplifier that boosts the electrical signal, a receiver that converts the amplified electrical signal back into sound, and a power supply or battery. Most hearing aids have a volume control.
