At point A, 3.20 m from a small source of sound that is emitting uniformly in all directions, the intensity level is 51.0 dB. a) What is the intensity of the sound at A? I got I = 1.26×10−7 W/m2 and it is correct. b)How far from the source must you go so that the intensity is one-fourth of what it was at A? I got R1 R1 = 6.40 m and it is correct. c) How far must you...
