Sound Absorption of the Absorber Composed of a Shunt Loudspeaker and Porous Materials in Tandem

To investigate the sound absorption of the absorber composed of a shunt loudspeaker (SL) and porous materials (PM) in tandem, the normal absorption coefficients for six samples of different groups of parameters are measured using impedance tubes. It is shown that a composite structure consisting of...
