Abstract: A sound control module is configured to determine N magnitudes for outputting a predetermined engine sound at N predetermined harmonics of a base frequency, respectively, where N is an integer greater than one. An adjustment module is configured to determine N magnitude adjustments for the N predetermined harmonics, respectively, based on a position of a compression ratio (CR) actuator configured to vary a CR of an engine. The sound control module is further configured to determine N adjusted magnitudes for the N predetermined harmonics based on: the N magnitudes for the N predetermined harmonics, respectively; and the N magnitude adjustments for the N predetermined harmonics, respectively. An audio driver module is configured to apply power to at least one speaker of the vehicle and output the predetermined engine sound based on the N adjusted magnitudes at N frequencies, respectively, corresponding to the N predetermined harmonics of the base frequency.

Abstract: A pass-through element for a motor vehicle front of dash panel system includes a body portion having an outer edge that surrounds a central web. A conductor pass-through member is provided in the central web, and a sound enhancing element provided in the central web alongside the conductor pass-through member. The sound enhancing element is configured and disposed to condition and conduct motor vehicle engine sound from an engine compartment to a passenger compartment through the motor vehicle front of dash system.
