A cylindrical silencer tube is fastened to the muzzle of a firearm or cannon. A quasi-parabolic reflector placed in front of the gun muzzle directs the main discharge gas and sound wave flow rearward to a tuned chamber behind the gun muzzle. The deflected sound waves strike the rear of the chamber and are directed back towards the next oncoming half cycle of sound waves. When the two out of phase waves collide at the entrance of the tuned chamber a cancellation of the noise occurs. The second section of the silencer is comprised of a series of chambers and semispherically shaped hollow baffles which direct part of the discharge gas and sound waves in a different and longer path from the main discharge gas and sound waves and then cause them to reunite in a chamber. The two out of phase colliding wave forms cancel each other. The spacing of the semispherical baffles is such that the discharge sound is raised to ultra sound.

A silencer to be fitted on the muzzle of a firearm for firing a projectile having a barrel of known caliber and outside diameter, said barrel having a longitudinal axis comprising: (a) a cylindrical silencer tube having a longitudinal axis; (b) means for attaching said cylindrical silencer tube to said muzzle of said firearm, such that said longitudinal axis of said cylindrical silencer tube is coaxially aligned with the longitudinal axis of said barrel; said attaching means for said cylindrical silencer tube having positioned in its interior a cylindrical mounting element disposed for threading upon the muzzle of said barrel, said cylindrical mounting element containing a central, threaded hole and a plurality of additional holes parallel to said longitudinal axis of said cylindrical silencer tube, said plurality of additional holes being substantially circularly disposed around said central hole of said cylindrical mounting element, said attaching means for said cylindrical silencer further having a tubular member, and said cylindrical mounting element having a shoulder for fastening thereto of said tubular member (1) said tubular member having an outside diameter and having an inside diameter large enough to pass over said barrel, said tubular member being secured at one end thereof to the shoulder of said mounting element, said tubular member having a flat annular disc member pressed opposite said cylindrical mounting element (2) said flat annular disc member having an inside diameter equal to said outside diameter of said tubular member and having an outside diameter equal to the inside diameter of said cylindrical silencer tube, said flat annular disc member being welded to said tubular member and to one end of said cylindrical silencer tube whereby the other end of said cylindrical silencer tube is supported in space by said cylindrical mounting element; and (d) a quasi-parabolic disc positioned within the interior of said cylindrical silencer tube, said quasi-parabolic disc having a centrally located hole for the passage of said missile and gas, and having a focus point at the end of said muzzle and an annular dispersion area at the center of said additional holes circularly disposed around the threaded hole of said cylindrical mounting element, whereby said quasi-prabolic disc directs said gas and sound waves from said muzzle back through said additional holes circularly disposed in said cylindrical mounting element.
