โœฆ Synopsis

A BS TRA C T By using the SEA method, the characteristics of structure-borne sound propagation in an existing building are analyzed. The calculated results of the sound-pressure level in the room are compared with measured values. An analytical model that simplifies the building is a group of rectangular rooms. For a certain type of building, the structure-borne sound propagation may be obtained by the use of a reduced two-dimensional model. It is found that the sound-pressure level in each room shows a linear attenuation with a roomlocation factor that is defined by the number of unit rectangular rooms and the regression coefficient relating to room dimensions. In this calculation, effects of the main structural wall and the blocking mass at each junction are taken into consideration.

Structural waves in a cylindrical shell can be decomposed into di!erent circumferential modes. The energies carried by these modes usually need to be quanti"ed and ranked for the purposes of noise and vibration control. In this paper, a theoretical basis is outlined for a method to measure the energ

There is increasing evidence that moments are signiยฎcant contributors in machine induced structure-borne sound. Omission of these components in prediction can therefore lead to an underestimate of total power in some cases, although it is recognised that considering all transmission paths in predict

The analysis of structure-borne sound transmission is obscured by the complicated nature of the dynamic interaction between source and receiver at each contact point. There is little measured data because of the practical difยฎculties in directly measuring forces and moments at the contacts. This is

Structure-borne sound transmission is a complex phenomenon, the accurate measurement of which requires advanced techniques. A multi-dimensional substitution source method is presented by which structure-borne sound transmission paths can be quanti"ed in practical situations where it is not possible
