J. Tiffen, an industrial psychologist, has defined it as —

“Noise is a sound which is disagreeable for the individual and which disturbs the normal WAY of an individual.”

According to the Encyclopedia AMERICANA:

“Noise by definition is unwanted sound. What is pleasant to some ears may be extremely unpleasant to OTHERS depending on a number of PSYCHOLOGICAL factor. The sweetest music, if it disturbs a person, who is trying to concentrate or to sleep, is a noise to him, just as the sound of a pneumatic riveting hammer is noise to nearly everyone. In other words any sound may be noise if circum­stances cause it to be disturbing.”

We can conclude by SAYING that any sound which is disagreeable to the individual and which hampers the normal way of the individual is noise.
