What is the function of a car muffler and how does it work?

[QUOTE="alexandria, post: 5456982, member: 586250"] "If you've ever heard a [URL='http://auto.howstuffworks.com/engine.htm']car engine[/URL]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." ok so what i am understanding from this, is that the car muffler is a set of tubes with holes in it. These tubes reflect the sound that is coming from the car engine, in a way that cancels most of the sound. This is a very broad understanding, but can someone explain it to me in more detail. The lesson that i am reading explained that a car muffler cuts the top half of the sound waves off, reducing its amplitude, therefore reducing the sound. A car muffler also relfects and absorbs sound coming from the engine to dampen the noise. i need a step to step process on how this works, does the car muffler first cut the top half of the sound waves off in the process of clipping, what happens first, second, third?
