When hair cells are harmed– by loud sound or ototoxic medications, as an example– the circuits in the brain don’t obtain the signals they’re expecting. This stimulates irregular activity in the neurons, which results in the impression of audio, or ringing in the ears.

The resulting electric sound takes the form of tinnitus– a noise that is high-pitched if hearing loss is in the high-frequency range and low-pitched if it’s in the low-frequency array. This type of tinnitus looks like phantom arm or leg discomfort in an amputee– the mind is generating unusual nerve signals to make up for missing input.
