A muffler is a component of a vehicle exhaust system; its purpose is to reduce the nose that is generated by the internal combustion engine. It is a component of the entire exhaust system which includes the exhaust manifold which is attached to the engine, the muffler, catalytic converter and pipes of various configurations. All of this is held to the underside of the vehicle with clamps and hanger brackets. Mufflers & exhaust in Mount Vernon WA often needs maintenance or replacement.
The workings of a muffler:
To fully understand how a muffler works you first need to have understanding of how sound is canceled, conceptually it is quite simple, the idea is to produce a sound which is exactly the opposite of the noise, the two simply cancel one another out and the result is silence. A muffler is not 100 percent efficient of course and that is why a small amount of noise is still heard.
Think of it this way, the engine produces a noise of a certain sound wave, the muffler produces a noise exactly opposite of the way, the two waves are out of phase and the noise is canceled.
If the car engine is running at maximum, producing its maximum amount of noise, the muffler will be producing the absolute minimum amount of noise. When your ear is subjected to these waves, the result is silence. In order for this to happen inside the muffler, there are tubes and baffles that have been engineered to suit the engine specifics. The internals of the muffler produce the sound waves that negate the engine sound.
This is how mufflers & exhausts in Mount Vernon WA work. The sound enters the core of the muffler; from there the sound moves to a resonance chamber. This resonance chamber has specific lengths of tubing; it is in this chamber that the negative wave is developed. As the sound waves leave the resonator they leave through the final pipe.
Although this type of muffler is by far the most common, there is another type which is often used on cars that have been “hopped up.” These mufflers are called glass packs and they muffle the sound by absorbing the waves and are not very efficient as a sound deadener.
