Man L27/38

Introduction
This paper describes typical structure-borne noise
levels from standard resiliently mounted MAN Gen-
Sets. The levels can be used in the project phase
as a reasonable basis for decisions concerning
damping and insulation in buildings, engine rooms
and surroundings in order to avoid noise and vibra-
tion problems.
References
References and guidelines according to ISO 9611
and ISO 11689.
Operating condition
Levels are valid for standard resilient mounted Gen-
Sets on flexible rubber support of 55° sh (A) on rela-
tively stiff and well-supported foundations.
Frequency range
The levels are valid in the frequency range 31.5 Hz
to 4 kHz.
