Cochlear and audio frequency

The sensing part is slightly different depending on the frequency of sound. Move the slide bar to check.


Inside our ears, there is a sensory organ that senses sound. The overall shape resembles a snail, called’cochlear’.
The cochlea is shaped like an elongated coffin. Inside, hair cells are placed.
When sound waves are transmitted to the cochlea, the thin-hair vibrate and sense sound.

The cochlea has mainly different parts of vibration depending on the frequency of sound. The lower the sound, the more vibration occurs inside the cochlea. Since the vibrating part is different depending on the pitch of the sound, you can use it to distinguish the pitch of the sound.

As you get older, the hair cells age and you may have trouble to hear the higher frequencies than younger people. Test how many Hz I can hear.
