Understanding how we hear is an important part of understanding how hearing aids work. In this article we will take some time to go over what sound is, how the ear picks up sound and how it sends sound to the brain.
What is sound?
Sound is invisible vibrations traveling through the air. When someone speaks, or a car honks it’s horn or anything else that can make “sound” a vibration is sent creating a disturbance in the air. The air carries that disturbance in the form of waves.
How does the ear pick up sound?
Our ear works as a funnel bringing sound waves into the ear canal and causes the eardrum to vibrate. Attached to the eardrum are three tiny bones, as the eardrum vibrates it moves those bones. Those bones then send the vibration to the cochlea causing the fluid inside to vibrate. The movement of the fluid causes the hairs inside the cochlea to bend.
How does sound make it to the brain?
When the hair cells bend they create signals that are picked up by the auditory nerve. The auditory nerve then sends signals to the brain where it is decoded as sound.
