A theoretical model is derived to calculate the specific acoustic impedance of the absorptive material covering the walls of a cavity. This model will allow the experimental determination of the specific acoustic impedance from the measurement of the reverberation time in a water-filled cavity. The model assumes a wall of low absorption. It can not be used for rigid or pressure release walls and grazzing incidence is excluded. 2013-02-15T23:29:33Z 2013-02-15T23:29:33Z 1991-12 Thesis http://hdl.handle.net/10945/27928 en_US Copyright is reserved by the copyright owner.
