Abstract:
1. An automotive vehicle, comprising: a chassis defining an engine compartment and a longitudinally spaced passenger compartment; an engine mounted in said engine compartment and being operable to generate noise energy; a transverse dual bulkhead plenum located at a forward position in said passenger compartment and being interposed between said engine compartment and said passenger compartment within the transfer path of the noise energy being transmitted from said engine to said passenger compartment so that the noise energy passes through the plenum to reach the passenger compartment; and a noise control system placed within said plenum to control the transfer of said noise energy through said plenum into said passenger compartment, wherein said noise control system includes sensors supported on said vehicle to sense operational conditions relating to said engine, said noise control system further including a device mounted in said plenum to generate counter noise to counteract said noise energy.
