9 Noise Emissions
The machine generates a work place Sound
Pressure Level (SPL) of 84.1 dB(A) when
processing a work piece.
The Sound Pressure Level at the Source (Lw)
is 102.1 dB(A) when processing a work piece.
Local conditions could increase the SPL,
which could cause hearing damage or loss.
The machine owner must provide suitable
protective gear to protect employees from
hearing damage, as required by local and
state laws and OSHA regulations.
Measurement margin of error = 4dB
Noise emission was measured according to
EN3746
Notes:
All listed values are measured noise emission
levels –they are not necessarily safe working
environment levels.
Local conditions, the proximity of walls and
ceilings, the type of wall, ceiling and floor material
as well other equipment in close proximity could
affect the total noise emissions at the work place.
The SPL values are provided as information only
and it is recommended that the machine owner
measure the actual local noise levels after
installation.
Machine is owner is responsible for providing
suitable protective gear depending on total noise
emissions and local and state laws and
regulations.
All OSHA regulations pertaining to noise
protection are to be adhered to.
