Though there is a dependency between the degree of the noise emission and the degree of the
noise disturbance it is not possible to use it reliably to determine if further precaution measures
are required or not.
The following factors influence the actual degree of the noise exposure of the operator:

Characteristics of the working area, e.g. size or damping behaviour,

other noise sources, e.g. the number of machines,

other processes taking place in proximity and the period of time, during which the
operator is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations.
This information about the noise emission should, however, allow the machine operator to eval-
uate the hazards and risks more easily.
CAUTION!
Depending on the overall noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protection.
We generally recommend the use of noise protection and hearing protection.
