The outer hair cells
http://www.cochlea.eu/en/hair-cells/outer-hair-cells-ohcs WebbOuter hair cells (OHCs) don’t transmit sound to the brain but are critical for mechanically adjusting vibration in the cochlea to amplify quiet sounds and dampen loud sounds. Loss of OHCs reduces vibration and causes hearing loss. OHCs are the most susceptible to damage and the most common cause of noise-induced hearing loss.
