摘要： On the basis of the observation that a fluid under pressure diffuses in a conical path with a certain divergent angle into a region of lower pressure, a silencer, through which a noise generating flow of a fluid is passed, is made up of a combination of concentric outer, intermediate, and inner shells respectively having shapes of hollow truncated cones with specific divergent angles in the discharge direction and provided on both surfaces or single surfaces thereof with sound absorbing layers of specific thicknesses.
