Abstract

Sound and vibration are intimately related to each other, yet they are two very different physical phenomena. In physics, sound is defined as the disturbance that travels in a compressible medium such as air in terms of a pressure (also called the longitudinal or compressional) wave. In physiology, sound is defined as the sensation of this pressure wave perceived by the brain auditory system of a human being.
