• G0900103 An Experimental Study on Acoustical Characteristics of Absorptive Material with Elastic Plate

抄録

Drum-like silencer has the structure where the membrane and the sound absorptive material are combined. The structure is placed in parallel to the propagation of sound wave in the duct sound field. The purpose of this study is to clarify the acoustic noise suppression mechanism of the combining a sound absorptive material and an elastic plate. We investigate vibration effect of elastic plate against the transmission loss experiment when sound wave enters parallel to the elastic plate is placed in a side of the duct. The double pair microphone method is used in the experiment. Large transmission loss can be achieved at the natural frequency of each plate.
