Abstract
In this paper, we describe acoustic characteristics of noise control device with absorptive material and an elastic plate. The devices with absorptive material and elastic plate are used in sound absorbing louver and various silencers to improve the performance of noise control. Configuration of simulation model consists of a rigid-walled square duct and the noise control device. Numerical analysis is carried out by finite difference time domain (FDTD) method for sound field and plate vibration. In order to verify the numerical results we examine the transmission losses of the sound absorbing devices and frequency responses from applied force to sound pressure at microphones in the duct. The calculated results and the experimental results of the transmission losses and the frequency responses show the same tendency.
