Wave Tube

The auditory pathway visualises the movement of invisible sound waves through the air. Go on, take a look and listen carefully! In contrast to the previous room, our perception is focussed on a single sound impulse.

Opposite the wave tube, the sound's journey is visually traced on five screens. Learn how sound travels from the outer ear to the brain:

1. Outer ear with auditory canal and eardrum:
at its longest diameter, the eardrum measures 9-10 mm

2. Middle ear with its tiny hammer, anvil and stirrup bones:
incidentally, these are the smallest bones in the body

3. Inner ear and cochlea:
location of the balance organ

4. Hair cells:
mechanical stimuli are converted into nerve activity

5. Auditory nerve:
the auditory nerve carries sound to the brain so that we can hear it

Did you know that…

at 20 degrees, sound travels through the air at a speed of 343 metres per second? And travels through water at a speed of 1,480 meters per second – so over 4 times as fast!
