1. A skip fire engine controller comprising:

  • a skip fire profile module arranged to monitor noise and vibration generated by one or more sources external to an engine and determine an operational firing fraction and associated cylinder load for delivering a desired engine output, wherein the selection of the operational firing fraction is based at least in part on whether noise and vibration generated external to the engine at least partially masks noise and vibration generated by the engine; and

    a firing controller arranged to direct firings in a skip fire manner that delivers the selected operational firing fraction.
