1. A method for controlling the operation of a motor vehicle noise management system, where the system comprises a motor vehicle cabin active sound management (ASM) system that uses an ASM controller to control the emission of sound from of one or more sound transducers that transmit audio signals in the cabin so as to alter vehicle powertrain-related sounds in the cabin, a mobile telephone system that is configured to receive incoming mobile telephone calls and transmit outgoing mobile telephone calls, and an audio head unit that is configured to command the ASM to cause the sound transducers to emit sound, the method comprising:

  • receiving, by the audio head unit, from the mobile telephone system, an indication that an outgoing mobile telephone call is being initiated; and

    in response receiving, by the ASM system, a command from the audio head unit, the command causing the ASM controller to cause one or more of the sound transducers to begin to emit sound that reduces the level of vehicle powertrain-related sounds in the cabin.
