Abstract (en)
[origin: WO2004076956A1] The invention relates to a method and a device for reducing noise from a gun. According to the invention, propellant gases escaping through the muzzle (3) of the gun's barrel (5) in connection with a firing are cooled by means of a coolant (2) in liquid or crystalline state to such an extent that a noise reducing pressure reduction of the propellant gases is obtained.
