(a) The rate of change of sound energy with density ɛ(t) in a live room is given by de Aɛc = II dt 4 where is the room volume (m³), A its average absorption (m²) and II the input power (W). Obtain the steady-state energy density, ɛ. when a loudspeaker in a room is continuously emitting sound with power 5 mW, when the room dimensions are 4 mx 5 mx 3 m and the average absorptivity is 0.4.
