Gas stream silencer

摘要

Noise and noise potential in a gas stream are controlled by series step treatment, each step accomplishing diffusion and smoothing of the flow with overall absorption of sound. The first stage provides a sturdy shock absorbing cushion to receive and mitigate rough blast while subsequent stages successively moderate and smooth the flow of the gas stream and absorb sound energy. Design criteria maximize diffusion and sound absorption while avoiding the creation of secondary noises within the unit.
