A muffler (USA name) or silencer (name in the United Kingdom and other areas) is a device for reducing the amount of noise emitted by a machine such as an internal combustion engine or a gun. The first was invented by Hiram Percy Maxim to silence guns. When used on internal combustion engines, the engine exhaust blows out through the muffler.

Mufflers usually contain a series of baffles to absorb sound. They are a common piece of equipment on automobiles, usually slung under the rear of a car, but many diesel-powered semi trucks have large mufflers mounted vertically behind the cab.
