What properties of sound determine the volume of sound? Is this affected by the motion of the sound source?

Question

naveenbabbar · Answer

your question is not complete. It should be, what properties of sound wave determine its intensity?
Intensity depends upon frequency of source, velocity of the wave, relative velocity between the source and observer, amplitude of the wave. 
yes it is affected by the motion of the sound source

Amplitude .
No it is not effected by the motion of the sound source.

naveenbabbar · Answer

I am not talking about dependence of amplitude on motion but due to motion the frequency heard by the observer will be different and hence the intensity of sound. All the factors ihave listed is for the depndence of intensity
