A multi-channel active acoustic attenuation system has a plurality of adaptive filter channel models each of which is intraconnected to each of the remaining channel models such that each channel model has a model input from each of the remaining channel models. The correction signal from each model output to the respective output transducer is also input to each of the remaining channel models, and each channel model has an error input from each error transducer. A generalized system is provided for complex acoustic fields.
