The present invention relates to a noise suppressor capable of reducing the noise of a fluid vented at high pressure and high mass flow rate from an industrial source, to the environmentally acceptable noise level. The invention combines two principles of dissipation of fluid stream energy: first, stream pressure is reduced by passing the stream through a swirler to split the stream into a number of smaller tangential streams which dissipate their energy along the spiral flow path due to friction; and next, the resulting streams pass through a tightly packed granular bed to reduce further the pressure and velocity of the exiting jet to atmospheric pressure and subsonic velocity, respectively. Such jet will generate much lower noise level, as compared to high pressure jet with cellular structure and supersonic velocity.
