A loudspeaker on a tall pole broadcasts sound waves equally in all directions. What is the speaker's power output if the sound intensity level is 113 db at a distance of 16 m?
The formula for a power output given sound intensity and distance is P = 4 π r² I where I is the sound intensity r is the distance Plugging in the value, P = 4 π (16)² (113) P = 363519.97 W
