Noise control
J. D. Turner, A. J. Pretlove · 1991
In common parlance the word ‘noise’ means sounds which are annoying and undesirable. Very often these undesirable sounds are also noises in the technical sense of having a broad frequency spectrum. The function of the professional noise control engineer is to minimise this noise. The preceding chapters have outlined the material which is necessary to an understanding of the physical generation, transmission and measurement of noise. This chapter shows how this material can be put to good use by the noise control engineer in solving practical noise problems in all their variety.
