WebMar 30, 2024 · Reactive mufflers consist of muffler units and are the most important method of attenuating the exhaust noise [2]. The acoustic impedance is transformed by the change in the pipe cross-sectional area, which results in the sound waves being reflected to reduce the noise [3]. To achieve better acoustic characteristics, designers often employ ...

WebMufflers that attenuate sound waves by interference are known as reactive mufflers. These devices generally separate the waves into two components that follow different paths and then come together again out of phase … Reactive mufflers are also commonly referred to as restrictive mufflers. The term “restrictive” has bad connotations, like restricting the flow of gasses out of the engine. All mufflers create some form of restriction as a byproduct of silencing unwanted sounds.
WebReactive Mufflers Reactive muffler contains many complex lumped elements for the wave to travel through. At the intersections, through a change in impedance the amount of wave energy transmitted is reduced. More of back pressure is created in these kind of muffler which affects engine performance drastically.
