Good, modern .308 suppressors typically have a net reduction of 25-30 dB measured 1 meter to the side of the muzzle, using the mil-spec procedure and equipment, with an absolute sound pressure of approx 130-137 dB at the same spot- using full power ammunition. The reader can determine if that means they "work" or not.
