An audio adjustment system for a vehicle includes a detection module that is configured to receive an image and detect a face of at least one of a passenger of the vehicle and a pedestrian near the vehicle. An age estimation module is configured to estimate an age of the at least one of the passenger and the pedestrian based on the detected face. An adjustment determination module is configured to determine an audio adjustment parameter for an audio signal based on the estimated age of the at least one of the passenger and the pedestrian.

Audio adjustment system

A vehicle and an associated method for augmenting audible sound generated in a passenger compartment by operation of first and second torque machines are described. The passenger compartment includes an audio speaker that is operably controlled by a controller that is also is in communication with the first and second torque machines. The controller includes an instruction set that is executable to determine first parameters associated with audible sound generated by operation of the first torque machine and determine second parameters associated with audible sound generated by operation of the second torque machine. A desired audible sound in the passenger compartment is determined. The audio speaker is controlled to generate a correction tone based upon the first parameters, the second parameters and the desired audible sound in the passenger compartment.

Method and apparatus for mitigation of noise generated by two torque machines

A method of controlling audio within a vehicle. The method includes determining a selectable driving mode, ascertaining an operating state of an engine in the vehicle, and identifying at least one of an engine start status and a drivetrain status of the vehicle. In response to at least one of the determining, ascertaining, and identifying, selecting a predetermined sound to be output within a passenger cabin of the vehicle; and applying a signal to a speaker of the passenger cabin of the vehicle based on the predetermined sound.

Pop and burble condition detection and calibration modification

An audio system of a vehicle includes a detection module configured to detect an occurrence of a sound when a pressure measured by an exhaust pressure sensor in an exhaust system is greater than a predetermined pressure. A sound control module is configured to, in response to the detection of the sound, increase a magnitude of a predetermined sound to be output within a passenger cabin of the vehicle. An audio driver module is configured to apply power to a speaker of the passenger cabin of the vehicle based on the predetermined sound.

Engine sound production systems and methods

An engine sound enhancement system includes a conduit in communication with at least one of an intake manifold and an exhaust manifold of an engine. An interface is arranged at least one of within the conduit and between an inlet of the conduit and the at least one of the intake manifold and the exhaust manifold. The interface is responsive to pulses within the at least one of the intake manifold and the exhaust manifold, wherein the interface is configured to transfer the pulses into the conduit.
