The action values for noise exposure are set to:
a)lower action value for working conditions in group I:LEX,1h = 55 dB
b)lower action value for working conditions in group II:LEX,1h = 70 dB
c)lower action value for working conditions in group III:LEX,8h = 80 dB
d)upper action values:LEX,8h = 85 dB and
LpC,peak = 130 dB
For working conditions in groups I and II, noise from the worker’s own activities shall not be a part of the assessment for the lower action values, provided that the worker can disrupt the noise. For mess rooms and recreation rooms, only background noise from installations, adjacent premises and surroundings shall be included in the assessment.
