About hearing

Hearing is the process of perceiving sound. A hearing loss can restrict communication and social interaction with others causing quality of life to suffer.

How does hearing work?

Sound waves travel down the ear canal and hit the eardrum, causing it to vibrate. These vibrations set the fluid of the cochlea into motion which stimulates 15,000 sensory cells, called “hair cells”, that convert the vibrations into electrical signals. The brain processes this raw data, making it possible to hear and enjoy things like music or an engaging conversation.

Physiology of hearing

Your ear can be divided into 3 parts. The outer ear and middle ear help collect and amplify sound. The inner ear converts sound waves to messages that are sent to the brain.
