Although the human ear collects sounds ranging from 100-20,000 Hz, it amplifies the 2-5 kHz frequency range where much of the important speech information registers. The intensity of sound or sound pressure level (SPL) is measured in decibels (dB). ...

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.
