Hearing Test

Test your hearing with the audiometer! It measures a property known as the "hearing threshold", i.e. the lower limit that you can hear at a certain frequency.

How hearing works:

1. Sound enters the ear canal. The sound waves travel along the canal and reach the eardrum.
2. In the middle ear, the eardrum is disturbed and vibrates against three tiny bones, the hammer, anvil, and stirrup.
3. Fluids in the inner ear vibrate. The vibrations move through the fluid in the spiral shaped inner ear – also known as the cochlea – making the small hairs of the cochlea move. The hairs absorb the vibrations and transform them into chemical signals for the hearing (auditory) nerve.
4. The auditory nerves communicate with the brain. The auditory nerve then sends the information to the brain with electrical impulses, where they are interpreted as sound.
