Geometry:
Cubic cavity (1 m * 1 m * 1 m)

Boundary condition:
All faces are rigid boundaries. A point source (S) is located at (0, 0, 0), and produces the impulse at t = 0.

-Task A-

Impulse response:
Input: volume acceleration [m3/s2] of the point source. Output: sound pressure [Pa] at 3 points (0.5, 0.5, -0.5) (R2), (0, 0, 0.5) (R3) and (0.4, 0.3, 0.2) (R4).
