Here in this picture the steps of how the sound waves from the hearing aid is being heard by the ears. First, the sound waves from the hearing aid is sent to the eardrums which vibrate and send the vibrations to three bones. Then these bones send the vibration to the cochlea where the sound energize tiny hairs to emancipate messengers called neurochemical messengers. Lastly, these neorochemical messengers carry electrical signals to the brain where these signals are turned into words that are scrutable.
