Abstract

Sound is a physical phenomenon produced by the vibration of matter, such as a violin string, a hand clapping, or a vocal tract. As the matter vibrates, the neighboring molecules in the air vibrate in a spring-like motion creating pressure variations in the air surrounding the matter. This alteration of high pressure (compression) and low pressure (rarefaction) is propagated through the air as a wave. When such a wave reaches a human ear and is processed by the brain, a sound is heard.
