Chapter 16, Problem 16.26(choose chapter or problem)
Two observation points are located at distances r1 and r2 from a source of sound. The sound spreads out uniformly from the source, and there are no reflecting surfaces in the environment. The sound intensity level at distance r2 is 6 dB less than the level at distance r1. (a) What is the ratio I2 /I1 of the sound intensities at the two distances? (b) What is the ratio r2 /r1 of the distances?
