Motor vehicle noise management
First Claim
1. A method comprising:
- receiving a first signal that indicates that an outgoing telephone call is being initiated; and
in response to the first signal, generating a second signal that, when processed by a controller of an active sound management (ASM) system for a motor vehicle, where the ASM system is adapted to command a sound system of the motor vehicle to provide signals to a vehicle sound transducer, causes the ASM system to cause the sound transducer to begin to emit sound that reduces powertrain-related sounds at one or more seating positions within a cabin of the motor vehicle that includes a plurality of seating positions.

Abstract
A device and method that is configured to control the operation of a motor vehicle cabin active sound management (ASM) system that uses an ASM controller to control operation of one or more sound transducers that transmit audio signals in the cabin so as to alter vehicle powertrain-related sounds in the cabin, wherein the motor vehicle further comprises a mobile telephone system that is configured to receive incoming mobile telephone calls and transmit outgoing mobile telephone calls. The device can include a controller that is configured to receive from the mobile telephone system an indication that a mobile telephone call is incoming or an outgoing call is being initiated. After receiving the indication, the subject controller commands the ASM controller to cause operation of one or more sound transducers such that the level of vehicle powertrain-related sounds in the cabin is reduced.
