In this paper the extension of the average zones of quiet produced in a diffuse acoustic field is studied when the acoustic pressure is cancelled at a point near a reflecting surface by using a remote secondary source. Analytical expressions for the extension of the zones of quiet generated when the

In a local active noise control system the pressure signal from a single microphone is usually taken as the error signal and cancelled by the action of a secondary source to create a zone of quiet. In this paper it is shown that the 0022-460X/99/110085
