Geometry:
A thin plate (1 m*1 m) on the infinite rigid baffle

Boundary condition:
Boundary condition of the plate is simply supported edge. All surfaces on the baffle are rigid boundaries.

Physical properties of the plate:
Thickness : 0.01 m
Young’s modulus : 7.5*1010 N/m2
Poisson’s ratio : 0.22
Density : 2500 kg/m3
Loss factor : 0.002

-Task A-

Impulse response :
Input: vibration acceleration [m3/s2] of the point source Output: sound pressure [Pa] at R1(0.5, 0.0, 0.0) and R2(0.5, 1.0, 0.0).
