Analysis of the influence of the layer adjustment design of the plate absorptive damper on noise reduction
Abstract eng: The paper deals with practical experience with measurement of acoustic power of the model - annular plate – while using plate absorptive dampers of the same area dimensions, but of different adjustment design of damping layers. During measurements, the model was excited by dynamic exciter using random signal and the acoustic power was determined by means of measuring acoustic intensity in individual points. The paper deals with relationship between adjustment of damping layers of the plate damper and its contribution to the reduction of acoustic emission.
