Characterisation of Structure-Borne Sound Source Using Reception Plate Method

Abstract EN

A laboratory-based experiment procedure of reception plate method for structure-borne soundsource characterisation is reported in this paper.

The method uses the assumption that the inputpower from the source installed on the plate is equal to the power dissipated by the plate.

In thisexperiment, rectangular plates having high and low mobility relative to that of the source wereused as the reception plates and a small electric fan motor was acting as the structure-bornesource.

The data representing the source characteristics, namely, the free velocity and the sourcemobility, were obtained and compared with those from direct measurement.

Assumptions andconstraints employing this method are discussed.
