Consider a room of dimensions 8 m × 6 m × 4 m (high), the absorption coefficient for the floor is 0.02, for the walls 0.04, and 0.15 for the ceiling. An omni-directional sound source with a sound power of 0.038 W is located in the room centre. Calculate: (i) the steady reverberant sound pressure level; (ii) the room radius (i.e., the distance from the source at which the direct and reverberant sound pressure levels are equal).
