2. A person initially stands 3.60 m from a source of 245 Hz sound, emitting equally in all directions. The person hears a sound of 55.0 dB. The person slowly walks toward the source of the sound at 2.00 m/s. The person stops at a final position that is a distance of 1.80 m from the source. a. Find the power of the emitted sound. _____________________________ b. Find the sound intensity at the final position. _____________________________ c. Find the sound...

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...
