... Why does our hearing deteriorate with age? The cochlea is the spiral-shaped part of the inner ear. It contains 10,000 hair cells, which move in response to sound waves, turning vibrations of the air into electrical signals and sending messages to the brain. When high frequencies enter the ear, they ...

Sound and Hearing
... What range of frequencies can you hear? Humans can only hear sounds of certain frequencies. The range of frequencies a person can hear is called their hearing range. Hearing range can be tested using a pitch sweep, in which the frequency of a sound wave is gradually increased. This can be created u ...

Sound

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. In physiology and psychology, sound is the reception of such waves and their perception by the brain.
