Question

When steady-state conditions are reached in a live room, the sound pressure level is

74 dB re 20 muPa. (a) If the average absorptivity of the walls is 0.05, what is the rate

at which sound energy is being absorbed per square meter of wall surface? (b) If the

total area of absorbing surface in the room is 50 m^2, at what rate in watts is sound

energy being generated in the room?
