2.3 What is noise?

Sound is what we hear. Noise is unwanted sound. Noise is an important form of pollution caused by unwanted sound.  The difference between sound and noise depends upon the listener and the circumstances. Rock music can be pleasurable sound to one person and an annoying noise to another. In either case, it can be hazardous to a person's hearing if the sound is loud and if he or she is exposed long and often enough.

NOISE IS LIKE BEAUTY – IT IS IN THE EAR OF THE BEHOLDER

Noise can be continuous, variable, intermittent or impulsive depending on how it changes over time. At low levels noise can be a nuisance, but exposure to sustained high levels, for example in a noisy workplace, can cause hearing loss. Impulsive noise, such as the sound of a pneumatic tool, or tonal noise, such as the whine of a machine, can be particularly irritating. But what some people consider as noise, others can tolerate, or may even like, and so the study of noise has to recognize these different subjective responses.
