5.3.9 INFORMATION ON THE NOISE LEVEL OF THE MACHINE
Figure 44 illustrates the location of the points where the phonometric testing took place,whereas Table 14
shows the LAeq (A-weighted Equivalent Sound Level) values measured for a machine model “SYNCRO M”.
The measurements were taken using an Amprobe SM-10 sound level meter, compliant with IEC651 type 2,
ANSI S1.4 Type 2, JISC 1502.
The maximum error of the measurements can be estimated in 2 dB [A].
Conditions of measurement (in compliance with the provisions of harmonised standard EN 12042:2020, Annex
A):
- machine running while empty at the maximum operating speed
- microphone positioned at 1.6 m from the ground and at 1000 mm from the machine
- distance of the microphone from the external profile of the machine:
1000 mm for points 1-2-3-4
300 mm for points 5-6
- presence of a background noise characterized by LAeq = 35.3 dB [A]
- duration of each measurement: > 30 seconds (approx.60 seconds)
The LAeq A-weighted Equivalent Sound Level can be reasonably considered less than 70 dB[A] for all the
dividers presented in this manual in the light of the values measured for the above-mentioned machine and in
consideration of the strong similarities that characterise the different versions of the machine
