Abstract
A noise reduction device designed for use with air rifles and sub-sonic applications is disclosed. The noise reduction device includes a plurality of collinear rings, each having a plurality of filaments fixed thereto in a radial configuration, so as to define an opening at the center of each of the rings.
Claims19
An apparatus, comprising:
- a plurality of rings, a center of each ring of the plurality of rings being collinear,
- wherein each ring of the plurality of rings includes a plurality of flexible filaments fixed radially to the ring toward the center of the respective ring such that the filaments of the plurality of flexible filaments are arranged to move in response to a gas passing through the filaments, a length of each filament being a fraction of a radius of the ring such that the plurality of filaments defines an opening at the center of the respective ring;
- and
- a coupler for coupling the plurality of rings to a muzzle end of a barrel of a gun.

A noise reduction apparatus, comprising:
- a plurality of connected rings arranged in a helix comprising a spring, a center of each ring of the plurality of rings being collinear, and each ring comprising a coil of the helix,
- wherein each ring of the plurality of rings includes a plurality of filaments fixed radially to the ring toward the center of the respective ring, a length of each filament being a fraction of a radius of the ring such that the plurality of filaments defines an opening at the center of the respective ring;
- and
- a first tube surrounding the plurality of rings such that the rings of the plurality of rings are free to move in a spring motion within the first tube, the first tube including a coupler at a first end of the first tube and a muzzle opening at an opposite end of the first tube corresponding in location to the opening at the center of the plurality of rings, the coupler configured to couple the first tube and the plurality of rings to a muzzle end of a barrel of a gun.
