Abstract: A selectively tunable exhaust noise attenuation device includes a body having an outer surface and an inner surface that defines an exhaust volume. An inlet is coupled to the body and fluidically connected to the exhaust volume. A first outlet is coupled to the body and fluidically connected to the inlet and selectively fluidically connected to the exhaust volume and a second outlet coupled to the body and fluidically connected to the exhaust volume. A first conduit including a primary exhaust gas flow path directly fluidically connects the inlet and the first outlet. A second conduit includes a first end and a second. The second conduit defines a secondary exhaust gas flow path. A valve is fluidically connected to one of the first and second conduits. The valve is arranged laterally off-set of the primary exhaust gas flow path.

Abstract: An audio system of a vehicle includes a total frequencies module that selectively varies a total number of output frequencies based on one or more present operating parameters of the vehicle. An allocation module, based on one or more present operating parameters of the vehicle, determines an allocation indicative of: (i) a first portion of the total number of output frequencies allocated to outputting first predetermined sounds for internal combustion engine operation; and (ii) a second portion of the total number of output frequencies allocated to outputting second predetermined sounds for electric motor operation. Based on the total number and the first and second portions, an audio driver module applies power to speakers of a passenger cabin of the vehicle to: (i) output first predetermined sounds at harmonic frequencies of the internal combustion engine; and (ii) output second predetermined sounds at harmonic frequencies of the electric motor.

Abstract: Methods and apparatus are provided for controlling noise in a compartment. The audio system includes an error microphone configured to receive sounds and generate an error signal corresponding to the received sounds. A processor in communication with the error microphone is configured receive the error signal from the error microphone and generate a noise-canceling signal based at least in part on the error signal and an acoustic transfer function. The audio system also includes a loudspeaker in communication with the processor to receive the noise-canceling signal and produce a noise-canceling sound wave based on the noise-canceling signal. The processor is also configured to receive at least one audio signal different from the error signal and to modify the acoustic transfer function utilizing the at least one audio signal.

Abstract: A control system for a vehicle having a fixed gear transmission and an engine that outputs an actual RPM signal is provided. The control system includes a vehicle bus, a shifting module, a simulated RPM module, and an engine sound enhancement (“ESE”) module. The vehicle bus transmits a signal indicating a plurality of operating conditions of the vehicle. The shifting module receives the signal from the vehicle bus to determine if the operating parameters of the vehicle indicate that a gear shift by the fixed gear transmission is imminent within a predetermined amount of time. The simulated RPM module is in communication with the shifting module for generating a simulated RPM signal if the gear shift is imminent. The simulated RPM signal has a greater increase in engine RPM with respect to time prior to the gear shift compared to the actual RPM signal.
