Abstract
A supercharger is provided, comprising a plurality of rotatable supercharger rotors each having a plurality of interleavable lobes configured to move air from an inlet to an outlet of the supercharger. Inner chambers in the lobes define an end opening and perforated end faces, at the end openings defining at least one port, having a length and a diameter. The at least one port is configured to operate with an associated air mass in the inner chamber to attenuate sound adjacent to the end opening.
