Geometry:
Spherical surface (1 m in diameter) in the free field.

Boundary condition:
The surface is rigid boundary. A piston source (0.2 m in diameter) (S) is located on the sphere, and produces the impulse at t = 0.

-Task A-

Impulse response:
Input: vibration acceleration [m/s2] of the piston face. Output: sound pressure [Pa] at 3 points (0, 0, 1) (R2), (0, 1, 0) (R3) and (0, 0, 10) (R4).
