The sound intensity is `0.008W//m^( 2)` at a distance of 10 m from an isotropic point source of sound. The power of the source is

A person is standing at a distance D from an isotropic point source of sound He walks 50.0 m towards the source and observes that the intensity of the sound has doubled. His initial distance D from the source is

What is the intensity at radial distances (a) 2.50 m and (b) 6.00 m from an isotropic point source of sound that emits energy at the rate 12.0 W, assuming no energy absorption by the surrounding air?

A source of sound operates at 2.0 kHz, 20 W emitting sound uniformly in all direction. The speed of sound in air is 340 m s^(-1) at a distance of air is 1.2kgm ^(-3) What is the intensity at a distance of 6.0 m from the source ?

Find the damping coefficient v of a sound wave if at distances r_(1)=10m and r_(2)=20 m from a point isotropic source of sound the sound wave intensity values differ by a factor eta=4.5 .
