What is a Muffler and How Does It Work?

A muffler or a silencer is a device for reducing the noise that is emitted by the exhaust of an internal combustion engine.  Mufflers are installed within an exhaust system of most internal combustion engines.

The muffler is engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting.

When it’s installed, the noise of the burning hot exhaust gas leaving the engine at high speed is abated by a series of passages and chambers lined with roving fiberglass insulation and/ or resonating chambers which are harmonically tuned to cause destructive interference wherein opposite sound waves cancel each other out.

With this explanation above, using a muffler or silencer, you can easily reduce a generator noise by a couple of decibels.

The mufflers covered in this guide can all be used for reducing generator noise.
