A woman stands a distance d from a loud motor that emits sound uniformly in all directions. The sound intensity at her position is an uncomfortable 2.12 x 10-3 W/m2. At a position twice as far from the motor, calculate the following. (a) the sound intensity W/m2 (b) the sound intensity level relative to the threshold of hearing dB
