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?

Respuesta :

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
