1. An automotive vehicle, comprising:

  • a chassis defining an engine compartment and a longitudinally spaced passenger compartment;

    an engine mounted in said engine compartment and being operable to generate noise energy;

    a transverse box-like structure interposed between said engine compartment and said passenger compartment within the transfer path of the noise energy being transmitted from said engine to said passenger compartment; and

    a noise control system placed within said box-like structure to control the transfer of said noise energy into said passenger compartment, said noise control system including;

    sensors operable to ascertain the acoustic environment of the vehicle and generate a signal indicative thereof;

    a controller operable to generate a mathematical model of the acoustic response from the signals generated by said sensors to define a predicted sound energy level therefrom; and

    a counteracting noise generating apparatus disposed within said box-like structure and being operably connected to said controller to produce a counteracting sound wave for the predicted sound energy level.
