1. An apparatus for controlling a sound field in auditoriums having at least a stage area and a main audience seating area, comprising:

  • a first assisted acoustics means comprising;

    a first input means for inputting acoustic energy in the stage area;

    a first control means for electrically controlling the acoustic energy input by said first input means;

    a first output means for outputting the controlled acoustic energy of said first control means to the main audience seating area;

    a second assisted acoustics means comprising;

    a second input means for inputting acoustic energy in the main audience seating area;

    a second control means for electrically controlling the acoustic energy input by said second input means;

    a second output means for outputting the controlled acoustic energy of said second control means to the stage area;
