2 A stereo speaker (considered a small source) emits sound waves with a L power output of 35.9 W. (Assume that the sound is emitted uniformly in all directions from the speaker.) (a) Find the intensity 10.5 m from the source. mW/m (+0.2 mW/m) (b) Find the intensity level, in decibels, at this distance. dB(+0.2 dB) (c) At what distance would you experience the sound at the threshold of pain, 120 dB? m (+0.02 m)
