Reactive muffler
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 ... Webreactive muffler [ rē′ak·tiv ′məf·lər] (engineering) A muffler that attenuates by reflecting sound back to the source. Also known as nondissipative muffler. McGraw-Hill Dictionary …
