Abstract
The requirements of a loudspeaker-enclosure-microphone system model are reviewed. It is shown that decoupling of the loudspeaker and the microphone requires an adaptive system with an impulse response of several-hundred-microsecond duration. Means to solve the adaptation problem are described
