2.4 - NOISE LEVEL
LpA = This value indicates the maximum sound
level perceived by the operator calculated by
making a worst case assessment at the 4 points
around the machine being tested.
Lwa = This value indicates the sound level
outside the machine and refers to the noise
perceived by those who are in the vicinity of the
work area.
Standards:
• S.I. 2008 No. 1597
Moreover, the LpA values have been taken at greater distances, resulting in 89 dB(A) at five metres and
80 dB(A) at thirty metres.
ALWAYS WEAR PROTECTIVE EARMUFFS AS THE MEASURED NOISE
VALUES REQUIRE NOISE PROTECTION DEVICES TO BE USED.
