A loudspeaker emits sound waves isotropically (uniformly in all directions). The average acoustic power delivered by the loudspeaker is P = 5.00 W . There are two 1. S_av listeners, one is at a distance R¸ =12.0 m , and the other is at a distance R, = 24.0 m. a. What is the intensity of the sound (in W / m² ) at the listener A's position, I ?
