FIELD: machine building.
SUBSTANCE: noise suppressor consists of inlet branch and case out of porous material rigidly connected with branch. The case is made out of sound absorber in form of conic perforated coaxial external and internal bushings. A sound absorbing structure is installed between the bushings. The structure is made out of at least one shaped porous sheet. Profile of the sheet in cross section can be triangle, rectangular, trapezoid, in form of arcs of circles, and sinusoidal, while end surfaces limiting surfaces of a truncated cone are made out of porous material. Also porous casing in from of ellipsoid of rotation or porous spherical casing covers the case.
EFFECT: increased efficiency of noise suppressing.
