Its a 1/16 in pipe. To the opposite direction of the flow sound propagates at a frequency of 30-40Khz. On traversing some distance the amplitude of the sound dies.

I want to determine the amplitude variation of the sound in that pipe.

wat kind of physics can be assumed for this .

whether we have to use 2 domains?
