Abstract: This paper deals with the attenuation and performance of dissipative device like hybrid silencer involving coupled wave scattering for two different mode incidents. In particular device comprises inlet/outlet duct sections and a membrane attached internally to the outlet duct which may vary to tune the device. The solution process using the hybrid mode matching technique insight the physical situation of the underlying problem. The power distribution between the fluid regions and the membrane(s) is discussed numerically. We also confirm the validation of power balance as a fundamental property of the truncated system.
