Noise area

A noise area is an area where noise is created and the location-specific rating level reaches or exceeds 85 dB(A) or the maximum value of the non-evaluated sound pressure level of 140 dB. Employees who spend time in noise areas are in principle exposed to the danger of hearing damage. The duration of exposure and individual rating level are decisive for any possible hearing damage where no hearing protection is used. Where there are noise areas that must be marked, a noise reduction programme must be set up and implemented.
