Measurement and Evaluation of Noise and Discomfort 680586

The engineer is often faced with the problem of forecasting the effects on human beings of the sound produced by equipment operating within the environment in which they live or work. A detailed measurement of sound pressure levels throughout the frequency spectrum is necessary for a complete analysis, but the standard sound level meter is probably adequate for most purposes and nearly as accurate as more complex computations. This paper provides useful criteria for specifying performance of equipment or for limiting the exposure of human beings to noise in certain acoustical environments.
