Understand your hearing and meet the hair cells

Did you know?

When a sound goes into our inner ear, it stimulates the hair cells in the cochlea to transduce the sound wave into a electrical signal. When our brain receives the signal, it sends a message to let us know that a sound has come through. Most hearing losses are caused by hair cell damage.

Take Erdo's free hearing test regularly. Take care of the precious hair cells from now on.
