The muffler works by breaking up the sound waves travelling down the exhaust tube, and causing them to self-interfere. Imagine that you have a long straight channel of water in which ripples travel the length of it, so that, unimpeded, when it meets open water, it would form widening circles of ripples. If before it meets the open water, it enters a series of side baffles so that ripples start to disperse but only bounces back to the main channel, intefering with the ripples in it, a choppy attentuation occurring, so that by the time it meets open water, it does not have strong, well-defined ripples in which to form big radiating ripples. A muffler, as well as a gun silencer, works in this way, in that the geometry of the channel is deliberately broken up with side recesses to prevent clean wall reflections of ripples or sound.

That Silencer is called Muffler in european technology !!
If you've ever heard a car engine running without a muffler, you know what a huge difference a muffler can make to the noise level. Inside a muffler, you'll find a deceptively simple set of tubes with some holes in them. These tubes and chambers are actually as finely tuned as a musical instrument. They are designed to reflect the sound waves produced by the engine in such a way that they partially cancel themselves out.

Baffles. Baffling, isn't it?
