How do hearing aids work?

Hearing aids are small electronic devices that amplify and clarify sounds, helping someone with a hearing loss to hear better and participate more fully in life. Hearing aids come in all different shapes and styles that can be worn in or on the ear, but they're all made up of the same elements:

Hearing _aid


The microphone (or microphones) receives incoming sound from the surrounding environment and converts it into digital signal


The amplifier increases the power of these signals based on the specific hearing aid settings before sending to the speaker


The speaker turns the digital signals into sound waves and then sends them to the brain to be interpreted


The battery provides the power to the hearing aid


The microchip enables more sophisticated features in your hearing aid, e.g distinguishing between speech and background noise.
