<p>An active noise and vibration cancellation system with broadband control capability. A broadband disturbance signal detector (42, 42a) positioned within a closed compartment (41) such as an aircraft cabin or vehicle passenger compartment provides a signal representative of the frequency spectrum and corresponding relative magnitude of a broadband signal emanating from a vibration energy source to a controller. The controller (46) receives the broadband disturbance signal (44) as well as error signals from error sensors (52) which, by virtue of adaptive filters within the controller, enhance the cancellation capability of the control signals produced by one or more actuators (50) positioned within the compartment.</p> |
