A point sound source emits sound equally in all directions at the rate of 0.98 J/s. A nearby microphone has a surface with an area of 1.54 cm2 and is directed perpendicularly to the incoming sound wavefronts. The surface of the microphone is a distance of 2.13 m from the sound source. Find the average sound intensity that this microphone would measure (assuming it is perfectly accurate, and there is no background noise)
