||This chronological survey of the development of different techniques for analysing acoustic fields describes existing methods ranging from measurement of ambient sound pressure (e.g. at the operator's workplace), to methods for studying the mechanisms of machine noise generation at source. Particular attention is paid to the measurement of acoustic power and to source location techniques. The development of these techniques runs parallel to that of noise reduction techniques, which have been moving away from measures aimed at lowering noise exposure (personal protection, screens and hoods) towards decreasing noise emission at source (changes in the structure of noisy machinery).
