processes, and the length of time for which an
operator is exposed to the noise. Also the
permissible exposure level can vary from county.
This information,
however, will enable the user of
the machine to make a better evaluation of the
hazard and risk.

The quoted figures are emission levels and are not
necessarily safe working levels. Whilst there is a
correlation between the emission and exposure
levels, this cannot be used reliably to determine
whether or not further precautions are required.
Factors that influence the actual level of exposure
of work-force include the characteristics of the
work room, the other sources of noise, etc, i.e. the
number of machines and other adjacent
