3.2 - MACHINE NOISE EMISSION
The test conditions under which the phonometric survey and the calculation of the sonic
power were carried out comply with applicable regulations and directives and are described
in detail in the various technical reports kept by the manufacturer
.
In case of accidental and/or instrumental errors, the uncertainty relative to the values indicated
below is K= 2 dB.
L
pA
: A - WEIGHED AVERAGE EMISSION SOUND PRESSURE LEVEL
This is an indicator of what is perceived by the human ear and consequently constitutes the
value used to assess the operators’ exposure to noise.
L
pA
= 66 dB (A)
L
wA
: WEIGHED SOUND POWER LEVEL A ISSUED BY THE MACHINE IN THE ENVI-
RONMENT
L
wA
= 83 dB (A)
(See paragraph “SOUND POWER PLATE POSITIONING”).
3.3 - INFORMATION ABOUT VIBRATIONS
The vibrations have been measured in a typical condition of machine use, i.e. during work
and with operating working tools.
The tests have been done on a plane surface, with roadbed in good conditions.
The vibrations have been measured and rated according to the requests of the applicable
directive; they are described in detail in the relative technical report kept by the manufac-
turer.
The equivalent vibration levels produced by the machine in working conditions is:
- for the hand-arm system: lower than 2,5m/s 2 .
These values relate to the time of actual use of the machine.
They may be used only as comparison values and are not suitable to determine the operator’s
real exposure levels, which depend on the conditions and environment of use.
