regulations, and company policies when working above the floor level.

Sound pressure level
Fig. 3
The sound pressure level was measured at a distance of
3 ft
from the wire rope hoist.
The mean sound pressure level is calculated for one operating cycle (50% with maximum
permissible load, 50% without load).
Instead of stating an emission value based on a workplace, the values from Tab. 1 and
Tab. 2 at measuring distance
“h”
can be used.
