Answer to Question #2274 in Mechanics | Relativity for sabeen
You are standing 7.0 meters from a sound source that radiates equally in all directions, but it is too loud for you. How far away from the source should you stand to experience one third the intensity that you did at 7.0 meters? answer in meters
The power of sound depends on the distance from the source as 1/R2, thus I2 = 1/3 I1 1/d2 = 1/3 1/72; d2 = 147; d = 12.12 m. You should stand 12.12 m away from the source.
