8. A loudspeaker emits sound waves isotropically (uniformly in all directions). Listener number one, at distance R, = 20.0m, hears sound with an intensity (in decibels) B = 85.0dB. a.) What is the average acoustic power, P delivered by the loudspeaker? b.) At what distance, R,, from the speaker would the sound intensity be 6, = 52.5 dB?
