Into The Cochlea

Have you ever thought about how we are able to hear high and low tones?

A low tone is a slow vibration. Only slow vibrations make it into the depth of the inner ear, sometimes called the apex of the cochlea.

High tones are fast vibrations. They do not move very far into the inner ear.

Experience description

How does a cochlear implant take care of the wide range of tones - low, mid and high tones? Most importantly, a cochlear implant needs to consider the natural place for each tone in the inner ear.

Find out which parts of the sound activate which area in the inner ear.

Very low tones need to be transmitted to the inner most part of the cochlea.

If all parts of the cochlea are being stimulated, the world will sound the most natural.

Note that we are not trying to simulate the sound of a cochlear implant here, but to show which areas of the cochlea need to be stimulated.
