Abstract
An air induction sound modification system for an internal combustion engine includes a multi-frequency sound suppression unit having Helmholtz resonators and a multi-component expansion chamber. A sound generator, which functions to radiate sound at a desirable, tuned frequency, extends between the multi-function sound suppression unit and a second expansion chamber, such as an air cleaner box.
