At point A, 3.0  m from a small source of sound that is emitting uniformly in all directions, the sound intensity level is 53  dB. (a) What is the intensity of the sound at A ? (b) How far from the source must you go so that the intensity is one-fourth of what it was at A ? (c) How far must you go so that the sound intensity level is one-fourth of what it was at A ? (d) Does intensity obey the inverse-square law? What about sound intensity level? | Numerade
