  • Compact muffler having multiple reactive cavities providing multi-spectrum attenuation for enhanced noise suppression
    Patent number: 10161275
    Abstract: A reactive muffler having multiple structures tuned to multiple frequency ranges or characteristics, and thus providing attenuation over a band of frequencies broader than a conventional reactive muffler. The present invention provides such a muffler by providing structures internal to the muffler skin that define multiple different volumes/cavities, each of which is tuned to provide distinctly different attenuation characteristics. In effect, the inventive muffler acts as multiple distinctly different mufflers providing distinctly different noise attenuation, though packaged within a single muffler skin/body.
