When sound enters your ear those sounds or signals end up in the brain. Acoustic Energy vibrates down the ear canal against the eardrum, it is then changed into mechanical energy as it passes through the three small bones of the middle ear. Next it becomes hydraulic energy in the fluid fill tubes of the inner ear, the cochlea. Finally the sound wave, as it moves through that fluid, flows over microscopic inner hairs which change it into an electro-chemical-neural energy signal that flies up the auditory nerve into the complex receivers waiting in the brain. The brain can make no sense of ...
