| Summary: | A laboratory-based experiment procedure of reception plate method for structure-borne sound
source characterisation is reported in this paper. The method uses the assumption that the input
power from the source installed on the plate is equal to the power dissipated by the plate. In this
experiment, rectangular plates having high and low mobility relative to that of the source were
used as the reception plates and a small electric fan motor was acting as the structure-borne
source. The data representing the source characteristics, namely, the free velocity and the source
mobility, were obtained and compared with those from direct measurement. Assumptions and
constraints employing this method are discussed. |
