Cochlear Implants
... Sensorineural hearing: When the three small bones move, they start waves of fluid in the cochlea, and these waves stimulate more than 16,000 delicate hearing cells (hair cells). As these hair cells move, they generate an electrical current in the auditory nerve. The electrical signal travels through ...

The mechanics of hearing
... If we had no outer or middle ear and the oval window of the inner ear were directly exposed to sound waves transmitted through the air, only 0.1% of the sound energy would be transmitted through to the cochlea and the other 99.9% would be reflected. As a consequence, our hearing would be less sensit ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
