• The equation of motion for a flexible plate with porous layers mounted directly on its surfaces is derived by taking account of the interaction between the solid frame of porous material and the fluid in the pores. In the derivation of the equation of motion, the effects of transverse shear deformation and rotary inertia of the solid material itself and of rotary force by the in-plane motion of the fluid in the pore are neglected. By the use of the obtained equation of motion, the formula for the sound transmission coefficient through the composite plate is deduced for the oblique incident plane wave. Some discussions are made upon the increases of transmission loss by the application of the porous layers on the core plate and upon the reversibility in spatial arrangement of the plate for sound transmission.
