AUDITE IN AQUA

Normal hearing. (Air conduction)

The earcup captures the sound and through the ear canal it arrives at the eardrum, a tightly tensioned membrane that vibrates with the sound wave and

forms the seperation with the middle ear.

The middle ear, consists of the three bones, the ossicles: the hammer, the anvil and the stirrup. These bones start moving when the eardrum vibrates. This amplifies the sound.

The inner ear consists of the cochlea and the labyrinth. The auditory and balance nerves are attached to this.
The cochlea is filled with a special liquid. This contains a special membrane with small cilia. These cilia will start to move when the stirrup moves the fluid in the cochlea.
This provides a signal to the brain.

Bone conduction.

With bone conduction, the earpieces of the headphones vibrate on the bone directly around the ear.

In this way the cochlea comes into vibration and sound is transmitted.
Basically bone conduction skips the middel ear part and directly sends the vibrations to the inner ear.

The inner ear is also called 'auris interna'. It consists of the cochlea and the labyrinth.

The auditory and balance nerves are attached to this.

The cochlea is filled with a special liquid. This contains a special membrane with small cilia.

These cilia will start to move when the stirrup moves the fluid in the cochlea. This provides a signal to the brain.
