Measurement of structure-borne sound source strength with a reciprocal substitution method
conference paper
Machines are important sources of noise in buildings, ships and vehicles. In general such machines emit noise in at least two ways: directly into the surrounding air - this is called the air-borne sound emission, and through the supports and other mechanical connections into the surrounding structure - this is called the structure-borne sound emission. For enclosures other than the machinery space, the structure-borne noise emission is often the most important of these two types of emission. Noise control in such cases requires an appropriate description of that emission. The paper concerns a description of the source in terms of an equivalent excitation force which is acting on the structure on which the machine is mounted.
