  • Abstract:
    An active noise control system for effective control of higher order modes of noise propagation within a duct is disclosed. A plurality of error sensors is disposed within an error sensors plane, which plane is perpendicular to the longitudinal axis of the duct. The disclosed process and apparatus minimizes the mean square distance between the points of the area associated to each error sensor. The resulting arrangement of errors sensors optimizes the overall area that the error sensors can control and consequently the global efficiency of the controlling system.
