This means that a 1 kHz sine wave that produces a given sound pressure will sound louder than a 10 kHz sine wave which produces the same sound pressure. In addition the nature of the ear causes it to produce harmonic distortion of sound w ...

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.
