A concert loudspeaker suspended high off the ground emits 35.0W of sound power. A small microphone with a 0.800cm2 area is 53.0m from the speaker.
Homework Answers
intensity at microphone, I = P/A = 35/(4*pi*r^2) = 35/(4*3.14*53^2) = 9.92*10^-4 W/m^2
power through microphone = A*I = 0.8*10^-4*9.92*10^-4 =
7.936*10^-8 watts
