1. Sound Intensity, Sound Level A point source of sound emits sound waves uniformly in 3D space (or, isotropically) at a constant rate of 100 watts. At a certain radial distance away from the point source, you are told that the sound level is 150 dB. WT, I sturgis 952 a) What is the radial distance? b) In a time span of 10 seconds, how much sound energy is intercepted an area of 1 cm at the same radial distance
