Hearing

Human hearing involves a complicated process of energy conversion. This process begins with two ears located at opposite sides of the human head. The ability to use two ears for hearing is called binaural hearing. The primary advantages to binaural hearing are the increased ability to localize sounds and the increased ease of listening in background noise. Sound waves from the world around us enter the ear and are processed and relayed to the brain. The actual process of sound transmission differs in each of the three parts of the human ear (the outer, middle and inner ears).
