NOISE LEVELS

The manufacturer must inform the user concerning:
the equivalent continuous sound level (Laeq), if the latter exceeds 70 dB(A) at the work
-
station,
- the sound power level (LWA), if the Laeq exceeds 85dB(A) at the work station,
- the peak pressure level (Lpc), if it exceeds 135 dB(A) at the station,
- the measuring methods used.
REFERENCE STANDARDS: ISO 7960
- Operating conditions for noise measurements
Annex B one-face surface planers
Annex C one-face thicknessers
- NF S31-084 – methods for measuring sound levels in a working environment for purpose of
evaluating workers' daily level of sound exposure,
- NF S31-069 – test procedure for measuring noise emitted by machine tools.
DEFINITIONS
-Equivalent continuous sound level (LAeq) in dB(A) – the most frequently given figure
-Characterizes the receiver, gives the value received as a function of the environment, the
distance from the source and/or on the basis of a test procedure for a daily exposure of 8 hours.
-sound power level (LWA) in dB(A)
-characterizes the noise source, gives an intrinsic value defining the noise emitted by this
source independently of the environment.
The table below gives the following data for each work station:
- the equivalent continuous sound level based on the standard test procedures,
- the sound power level
- without load and without dust extraction,
- under load with vacuuming but without taking into account the noise of the dust extraction
itself.
The nature of the premise, the location of the machine within the premises and the presence of
a vacuum cleaner nearby can greatly influence the noise level. For example, for a cutting speed
of 20m/s of the thicknessing station and a dust extraction air velocity of 10 m/s instead of 20 m/s,
