Noise Emission Levels - Komatsu H70051 Series Operation & Maintenance Manual

NOISE EMISSION LEVELS

NOISE EMISSION LEVELS
Two signs are attached to the machine that state the noise level produced.
• Sound pressure level at the operator's station, measured
according to ISO 6396 (Dynamic test method, simulated
working cycle).
The maximum value of the standard deviation of the meas-
ured time-averaged A weighted emission sound pressure
level at the operator's position is 2.5 dB, in accordance
with ISO 11201.
• Sound power level emitted by the machine, measured ac-
cording to ISO 6395 (Dynamic test method, simulated
working cycle).
This is the guaranteed value as specified in European di-
rective 2000/14/EC.
This value includes an uncertainty of 2.5 dB.
