Abstract
A pair of loudspeakers can be used to actively control an incident acoustic wave in a duct, without generating reflections. An algorithm is presented for the adaptation of the digital controller driving the two loudspeakers, which minimises the outputs of two error microphones, one upstream and one downstream of the loudspeaker pair
