Noise legislation in South Africa was introduced in 1974. However, in industry, compliance with the recommended maximum equivalent noise level of 85 dB(A) is poor. The subject of noise exposure is reviewed briefly and a tentative proposal for a temporary raising of the statutory limit is put forward.
Different methods for measurement and assessment of industrial noise are discussed. It is shown, that momentary the best approach to stress caused by noise is the "Trakt-Maximalpegel-Verfahren" with a cycle time of 5 s. For more exact description of acoustic recording of sound level and harmonic analyzis are indispensable.
