Slow Water=slow Sound?

a: A muffler ~
b: the pool at the bottom of a waterfall

What: "Put another way, a muffler is like the pool at the bottom of a waterfall. A massive stream of loud, boisterous water falls in, but a slow, steady stream of water flows out. The key to designing a muffler is understanding how best to contain each shockwave without limiting the flow of the hot exhaust gases."

Car Mutes

a: The muffler ~
b: a mute stuck in the end of the horn

What: "The muffler is like a mute stuck in the end of the horn. There are all sorts of styles that create all sorts of sounds. Chambered mufflers are designed to use noise to cancel noise, dividing exhaust pulses and reflecting them back on one another to hopefully cancel themselves out."

Gun Noise

a: Gun muffler ~
b: automobile silencer

What: "The point is a gun muffler is like a automobile silencer. The gun muffler reduces muzzle blast noise and does nothing for action, bullet flight or impact noise just as a car silencer only reduces exhaust noise and does nothing for wind, engine, transmission or tire noise. I only use a silencer for reducing muzzle blast noise. If I want to reduce bullet flight noise then I will use subsonic ammo and a small bullet. Big bullets like 44 caliber and above make a very audible humming noise even when subsonic. If I want to reduce impact noise then i shoot a soft target like dirt and not steel."
