1. A vehicle, comprising:

  • a body having an exterior portion and an interior portion;

    a plurality of sensors installed on the vehicle, each sensor configured to detect noise existing in at least one of the exterior portion and the interior portion, and to output at least one noise signal indicative of the detected noise;

    a plurality of noise cancellation and enhancement (NCE) controllers in signal communication with at least one sensor among the plurality of sensors, each NCE controller configured to perform at least one noise management signal processing operation based on the at least one noise signal; and

    an automotive audio bus (A2B) interface configured to receive the at least one noise signal and deliver the at least one noise signal to the at least one of the NCE controllers,wherein the at least one noise management signal processing operation includes;

    comparing, with at least one of the NCE controllers, a first noise signal associated with the exterior portion to a second noise signal associated with the interior portion;

    generating, with at least one of the NCE controllers, a post-processed signal in response to phase-shifting the first noise signal based on the second noise signal; and

    converting the post-processed signal into an audio signal that is emitted into the interior portion of the vehicle such that the noise associated with the exterior portion is at least one of suppressed and enhanced.
