SILENCING SYSTEM WITH RESONATING ELEMENTS AT ACOUSTIC WAVE ANTINODES

An automotive internal combustion engine exhaust system is described in which the sound peak associated with the resonance of the tail pipe (between muffler and exhaust system outlet) is said to be controlled by connecting a quarter-wave tube to the exhaust pipe (between engine and muffler). The exhaust pipe length is selected to be resonant at the tail-pipe resonant frequency, and the quarter-wave tube is connected at an antinode.--JAG
