Abstract
A kind of active noise control system for broadband noise which applies to the ducts including both the short duct and long duct. The principle is to arrange a set of microphones at suitable positions for special combination and treatment on the acoustic signals and be separated with the acoustic states, including the howling, and the characteristic of transducer. Employing the online parameter adaptation to calculate the dynamic compensation value of transducer and output a suitable control signal to the transducer for the active noise elimination. The invention need not to compensate the acoustic state of ducts so greatly reduce the number of parameters and reduce the calculation and increase the convergence speed. And, the method is not related with the boundary conditions so it is rather effective.
