摘要

The influence of the sound radiation from surfaces is examined from a prediction of structure-borne sound. The level of structure-borne sound due to environmental ground vibration is shown from a Multiple Coherent Output Spectrum, which represents common elements of all input vibration signals. The use of the Multiple Coherent Output Divided Spectrum at each surface is examined. A parameter is proposed which shows the contribution of structure-borne sound from the each surface of the room. The theory is considered for a system consisting of six speakers equivalent to the six surfaces of the room, and prediction compared with experimental results.
