Occupational noise or workplace noise is becoming a more discussed issue as studies find the implication of long term  high noise environments on people’s hearing. There is an upper exposure action value of 85 dB (A) where there must be action taken to reduce the noise levels, hearing protection must be worn and access restricted. There is a lower exposure action value of 80 dB (A) where hearing protection must be provided. Noise measurements can be taken beside all major items of machinery to determine the potential trouble areas and peak noise levels can also be measured as there is a peak limit of 140 db (C).
