Methods are discussed for the identification and control of industrial noise. One method for characterizing the problem utilizes a sound level meter having A, B, and C weighted scales, which help identify frequency characteristics of the sound. A more detailed examination can be made through octave band analysis, which allows selective listening to the octave bands above and below 1,000 Hertz. Narrow band analysis is more efficient when there are a number of sound sources involved. Methods of monitoring sound levels are also discussed. Case histories are reviewed of noise control studies in a textile yarn spinning mill, a hosiery mill, a carpet manufacturer, and a nylon polymer chip cutter. In terms of cost effectiveness, the author suggests that the identification and characterization of major noise sources is of primary importance, if time and money are to be used effectively.
