FACTS AND FALLACIES OF NOISE CONTROL

Nine physical phenomena that may produce noise directly from an electrical input are briefly considered. Their significance is assessed and the practical situations in which they may occur are noted. Following some comments on instrumentation and test environment, details are given of tests carried out on small (1.5 kW) three-phase induction motors. It is concluded that noise-producing elements generally cannot be studied usefully in isolation from the complete assembly or the system of which the assembly is part. The immediate environment is also significant in determining the resulting sound levels.
