How Hearing Aids Works

A hearing aid is an electronic device that amplifies sound. When a hearing aid amplifies sound it makes the sound appear at an audible volume for the wearer. Without the volume amplified the wearer may not be able to hear the sound at all.

There are varying degrees of hearing loss. The technology used to improve hearing has led to a number of innovative devices that increase a person’s range of hearing.

Standard Hearing Aid Parts:

• Hearing aids have microphones. The microphone picks up sounds so it can convert them to electronic impulses.
• Hearing aids have an amplifier to increase the strength of the electronics impulses.
• Hearing aids have a receiver to transform the impulses back into sound waves so they can be redirected to their user.
• Hearing aids are powered by a small battery.

Optional Hearing Aid Parts:

• Some hearing aids have a computer chip that enables them to be programmed.
• Many hearing aids have a switch that controls the volume and power.
• Some hearing aids also have the option to change the listening environment. So, you have a more comfortable clarity for conversations, public places etc.
