We are also remarkably attuned to variations in sounds: For example, we easily detect differences among thousands of hum ...

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.
