-The occupational noise exposure level LEX, 8h measured for workers in each trade in two projects was calculated according to ISO 9612:2009
- workers from most trades at the construction site were exposed to elevated noise.
- differences in exposure level for the same trade between projects can be attributed to daily working time, working intensity and project scale.
- the occupational noise exposure indicator LEX, 8h for nine trades (except excavator operators, who experienced exposure
levels below the limiting value of 85 dBA)
