✦ Synopsis

At the design stage of many projects, the engineer is often asked to make a prediction of any resultant sound levels. To achieve this goal, the analysis needs to account for all the excitation sources and their interaction with all the transmission paths. Whilst for air-borne sound a source-path-receiver model is often employed with success, inherent physical problems have, to date, prevented a similar approach being adopted for structure-borne sound. In this paper the problems are reexamined with particular reference to the characterization of machines as structure-borne sound sources. A novel approach proposed by Mondot and Petersson for a single point and component of motion [1] is developed to include multiple points.
