Flexible Duct Silencer
Perforated on the inside and expanded to fit over existing ducts on the outside, these act as mufflers along the course of an exhaust path, typically deployed with heavy industrial machinery.
Perforated on the inside to act as a baffle against airborne noise, and expanded in radius to fit over existing ducts, flexible duct silencers act as mufflers along the course of an exhaust path, typically deployed with heavy industrial machinery.
Because they are designed to flex and bend, they will not only cut down on airborne noise passing through, but also can be shaped to channel the air. By curving an exhaust system to break the line of sight from one end to the other, air can be prevented from from picking up straight-line speed and the added sound that comes from that velocity.
