We generally classify sounds according to their frequency or in some cases how pleasant it feels to our ears.
In the first case, sound can be classified as either being high pitched (high frequency) or low pitched (low frequency). Going even further, sound can be divided into three different frequency levels; infrasonic, sonic or supersonic sound.
On the basis of its pleasantness, sound is generally considered as either being music or noise.
