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

Intensity of sound at a point is its distance from the source

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

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

Explain why the loudness of a sound note varies with the distance from the source of sound

If the distance between the source and the observer is doubled,the intensity of sound becomes

A person standing at distance r from a point source listen the sound emitted by the source. When person move to another point having distance (r )/(10) from the point source, then increase in sound intensity level is nxx10^(1) decibles value of n is ?

A person standing at distance r from a point source listen the sound emitted by the source. When person move to another point having distance (r )/(10) from the point source, then increase in sound intensity level is nxx10^(1) decibles value of n is ?

A person is standing at distance of r from a source of sound. The frequency and intensity of sound observed by him are f and I respectively. Now he moves with a uniform velocity away from sound source, then he will observers that -

A person standing at a distance of 6 m from a source of sound receives sound wave in two ways, one directly from the source and other after reflection from a rigid boundary as shown in the figure. The maximum wavelength for which, the person will receive maximum sound intensity, is
