Muffler
The back, bottom of your car houses the mufflers, which are a component of the exhaust system. They help to reduce engine noise and pollution from vehicles. To protect them from the heat and chemicals emitted by the exhaust system, they are built of steel and covered with aluminium. Mufflers are primarily employed to muffle the obnoxious noises that the engine's pistons and valves produce. A significant amount of the burned gases needed during combustion are discharged into the exhaust system each time your exhaust valve opens. Strong sound waves are produced as a result of the gas expulsion. One must comprehend how sound is produced in order to comprehend how a muffler scatters the sound waves produced by your engine. A pressure wave is what creates sound.
