A stereo speaker (considered a small source) emits sound waves with a power output of 22.4 W. (Assume that the sound is emitted uniformly in all directions from the speaker.) a) Find the intensity 10.5 m from the source. b) Find the intensity level, in decibels, at this distance. c) At what distance would you experience the sound at the threshold of pain, 120 dB?
