摘要：

This paper considers the minimization of total acoustic power radiated from a large duct opening. The authors propose a method employing an active noise control in order to minimize the total acoustic power by designing the duct opening, leading to change the complex pressure amplitude in the duct opening. This method was applied to the transformer noise radiated from a large duct end. The experimental result was confirmed by comparison with the simulation result.
