Components of a Hearing Aid:
-
Microphone: Captures external sound waves.
-
Amplifier: Increases the strength of the sound signals.
-
Receiver (Speaker): Converts the amplified signals back into sound waves.
-
Battery: Powers the device.
-
External casing: The outer shell that holds all components together.
How a Hearing Aid Works:
After receiving external sound waves, the microphone converts these sounds into electrical signals. The amplifier then increases the strength of these signals according to the user’s hearing needs and settings. The receiver converts the amplified electrical signals back into sound waves and delivers them into the wearer’s ear.
