A discussion on the origin and treatment of noise in industrial environments - On the effects of noise of fluctuating levels

Abstract Information in the form of sound waves is communicated as functions of frequency, intensity and time. In order to grasp these processes we must employ a three-dimensional representation. In a piece of orchestral music we regard the concerted playing and its changes from pianissimo to fortissimo as a pleasing sensation. The cumulative effect of machine and industrial noise, which may coincide with that of a piece of music, is found to be un-pleasant, annoying and damaging. The preceding papers have considered the damaging effects of noise which lead to deafness. The importance of frequency and its representation by the A weighted network and by limit curves, e.g. n.r. curves has also been treated.
