Occupational Noise
Occupational Noise
The occupational noise measurement is based on assessment of daily noise exposure level (LEX, 8h) defined by ISO 1999. The LEX,8h is basically a 8-hours extrapolation of LAeq measured over the working hours. The Directive set up limits for LEX, 8h: 87 dBA as the daily limit, 85 dBA as the upper action value and 80 dBA as the lower action.
