A loudspeaker supported well above the ground on a post is supplied with
8.5 W of electrical power. The speaker is able to convert
5.6% of that into sound power. (That number is known as
the speaker's efficiency.) If we assume that sound
radiates equally in all directions, what is the sound intensity at a
distance of 7.1 m?
Please help? :shy:
