The Hair Bundle Is an Amplifier of Sound

neuro scientist jim hudspith describes the sensory receptors in our ears, hundreds of microscopic hair cells that make up the hair bundle. These 16 thousand cells each send information about a particular sound that flows into the brain, and the brain then says, i heard a middle sea. I heard whatever tong it happens to be. When the amplification fails, our hearings sensitivity plummes. And so what exactly is happening in mary louise's ear, for example, in all our ears when when we hear and then when we lose our hearing? Answer is that that amplifier begins to burn out.
