Airborne noise emission
The A-weighted sound pressure emitted by this product is below 70 dB.
** The noise level can vary depending on the site.
The figures quoted are emission level 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. Factor that influence the actual level of exposure of
the workforce include the characteristics of the work room and the other sources of noise, i.e. the
number of equipment and other adjacent processes and the length of time for which an operator
exposed to the noise. Also, the permissible exposure level can vary from country to country. This
information, however, will enable the user of the equipment to make a better evaluation of the hazard
and risk.
