The ear's sensitivity to sound is controlled by outer hair cells

The human inner ear has a type of cell called the outer hair cell. These were thought to amplify sounds from the environment. However, a new study based on hearing in gerbils shows these cells are probably involved in regulating the sensitivity of the ear to sound. This could help find ways to preserve good hearing by protecting these cells from destruction.
