| Zusammenfassung | In residential and office buildings service equipment can be annoying if it produces noise. To avoid noise, especially structure-born sound noise, a prediction and calculation of sound power injected into the structure is necessary. Standard DIN EN 12354-5:2009 only provides little information regarding the characterization of a structure-born sound source. Especially for light weight structures, when the mobilities of source and receiver could match, a practical method for the power prediction is missing. But it is necessary for an accurate sound pressure prediction. This paper focuses the prediction of sound pressure levels in rooms due to structure-borne sound sources. For the characterization of the sources the "Two-Stage Method" (TSM) was used. TSM yields the characteristic source parameters and the characteristic structure-borne sound power of the sources. With these source parameters the sound pressure levels in a light weight test stand were calculated and they were compared with measurements. Furthermore it will be referred, if the prediction method in DIN EN 12354-5:2009 using TSM for source characterization is valid for the prediction of sound pressure levels due to structure-borne sound sources in light weight constructions. |
