Abstract
The silencer’s scheme in which the duct is divided by vertical bent partitions into ranges series of expansion chambers is presented. The silencer’s scheme parameters ensuring even noise reduction in a wide frequency range are calculated. Abilities of the reactive silencer in exhaust ventilation systems are shown.
