1. at point A, 3.00 m from a small source of sond that is emitting uniformly in all directions, the sound level is 53.0 dB.
a. what is the intensity of the sound at point A?
b. how far from the source would the intensity of the sound be one-fourth from the intensity at point A?
c. How far from the source would the sound level of the sound be one-fourth the sound level at point A?
