1.4 Measuringsurface soundpressure level
The gear unit has a measuringsurface soundpressure 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 soundintensity method.
The workplace of the operating personnel is defined as the area on the measuringsurface at a distance
of 1 metre in the vicinity of which persons may be present.
The soundpressure level applies to the warmedup 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 measuringsurface soundpressure level includes addon lubrication units, if applicable. With
outgoing and incoming pipes, the interfaces are the flanges.
The soundpressure 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 soundpressure levels.
