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.
