Webexposure levels for noise in the workplace. However, over long periods, repeated noise exposure at between 75 and 85 decibels may be a small risk to some people. With progressively increasing levels, the risk becomes greater. Workplace noise levels lower than 85 decibels are, therefore, desirable, if practicable. viii Web6 Sep 2012 · The symbol for the A-frequency and S-time weighted measurement is:- LASmax. As above, for a sinusoidal sound the peak value is 3dB higher than the Max level and this is the closest they can get to each other. For ‘normal’ environmental noise, the Peak value may be over three hundred times – or 30 dB – higher than the Max level.
