Quote: Electrochemistry

“In the human ear, sound is a mechanical movement of air molecules, bones, fluids and membranes. No such movement can stimulate brain cells to create the sensation of hearing. The brain responds not to vibrations but to electrical-chemical changes like those in a battery. There has to be a transducer, a device similar in purpose to a microphone, for converting mechanical energy into electrical energy. The microphone inside the human head is the microscopic organ of Corti. It is the essential link in the hearing. Outside it is only delicate machinery, inside only electrochemistry”.
