FIELD: mechanical engineering; mufflers.
SUBSTANCE: proposed reactive muffler contains cylindrical housing rigidly connected with end face intake and exhaust branch pipes. At least two disks with holes forming chambers are installed in housing square to direction of aerodynamic flow. Holes of disks are alternately displaced relative to axis of housing so that holes of two adjacent disks do not coincide. Ratio of length 
of housing to its diameter D lies with in range of optimum values 
Ratio of diameter D of housing to diameter 
of exhaust branch pipe lies within range of optimum values 
Ratio of diameter D of housing to diameter d of hole in disks lies within range of optimum values D/d=5.0-6.0. Ratio of diameter D of housing to length 
of chamber lies within rage of optimum values 
EFFECT: improved efficiency of noise damping owing to adjustment of chamber muffler by turning sound absorbing element.
