1.4 Measuringsurface soundpressure level
The gear unit has a measuringsurface soundpressure level at a distance of 1 m, which can be found in
tables 5 to 8.
The measurement is carried out to DIN EN ISO 9614 Part 2, using the soundintensity method.
The workplace of the operating personnel is defined as the area on the measuringsurface at a distance
of 1 metre in the vicinity of which persons may be present.
The soundpressure level applies to the warmedup gear unit at input speed n
1
and output power P
2
stated
on the rating plate, as measurement obtained on the Siemens test bench. If several figures are given, the
highest speed and power values apply.
The measuringsurface soundpressure level includes addon lubrication units, if applicable. With
outgoing and incoming pipes, the interfaces are the flanges.
The soundpressure levels stated in the table were obtained by statistical calculation by our Quality Control
Dept. The gear unit can be statistically expected to comply with these soundpressure levels.
