Sound waves are an integral part of human life and other living things; But not all types of sound waves are useful. Waves that are unwanted, unpleasant, and damaging are called Noise. The word "noise" is a misnomer. And other categories of sound waves are called music. All natural sounds, people talking and playing with special instruments are called music. Music is a pre-designed sound that has a certain order in its specific amplitudes, frequencies and intervals and has no destructive effect. Therefore, any sound that is outside this rule is also considered as sound. For example, shouting, playing music with unconventional instruments, and even recreational music and some inappropriate use of headsets can also damage the body and are classified as sound.
