The human ear is a complex organ and the sound heard from the two ears is combined in human brain. Humans can hear a variety of sounds and the difference between the loudest and faintest sounds that human can differentiate is about 120db (Decibels). It is a range of one-million in amplitude. Our ears can detect the change in loudness if there is a change of 12 percent in amplitude. Ears are sensitive organ and when listening to weak sounds the ear drum vibrates less than a diameter of a single molecule. the range of human hearing is 20 Hz to 20 Khz.
