Of course cannot, exact for, so called " muffle " just also compare informal style, more exact name should be " muzzle noise is restrained implement " , it can reduce muzzle noise on certain level only, and cannot comb-out it.
Generally speaking, the noise cent that when firearms shoots, gives out is 3 parts, it is the mechanical noise that rifle bolt gives out when mechanical reciprocate, 2 it is the sonic boom noise that when warhead breaks through velocity of sound, produces, 3 it is gunpowder gas develops a muzzle to bump all round give out when air explode earthquake wave noise. Noise of rifle bolt mechanical movement (what basically point to is to attack hammer to bump firing pin, firing pin hits the fire in a stove before fuel is added or guide gas piston reciprocate
Noise) eliminate very hard, because you do not have a law,lap in the firearms interior of narrow high temperature sound-absorbing material; The noise when warhead breaks through sonic barrier also cannot be eliminated, so breathed perhaps machine gun chooses breathed handgun mostly tailor-made subsonic speed is played, assure warhead initial velocity under velocity of sound; What muffle basically eliminates is warhead flies off when muzzle explode earthquake wave noise, roughly measure is the setting in the thing tubal account that grows quite in many amortization bowl or amortization cotton, the principle of amortization bowl is to connect overmuch layer amortize to lower air rate, and amortization cotton can make amortization effect much better -- below the case that taking integrated step, can reduce muzzle noise 30db left and right sides, this has been a more excellent numerical value. Besides reduce muzzle noise, muffle still can reduce the frequency of noise, will high frequency noise becomes relatively grave, the distance of transmission is closer also, be concealed more easily in all sorts of background noise, be differentiated to come out by auditive place of the person hard. Of course, there still is a few now more outstanding special small voice weapon, the 05 type of my army are for instance small acoustical machine gun, the voice of firing pin can be heard only on very close when fire distance.
Above is " army fierce a face " solve for you, if approve of replies, the head that welcomes to pay close attention to me date ^_^
