No, a flash suppressor does not make a gun louder. A flash suppressor is designed to direct the expanding gases from the muzzle of the firearm away from the shooter’s line of sight. This is done to reduce muzzle flash and help conceal the shooter’s location.
Muzzle blasts and noise are largely caused by the propellant gases escaping from the barrel after the bullet has left it. A flash hider or compensator can help redirect these gases away from the shooter, which will minimize both muzzle blast and noise.
