Abstract
The invention concerns a method and device for actively correcting acoustic properties of a listening zone () of an acoustic space (), comprising means for converting a signal to be reproduced () in an acoustic space (), means for attenuating resonance including at least means for measuring the perturbed sound signal (), means for processing an electric signal () and at least one secondary sound reproduction source (). The invention is characterized in that the means for measuring the perturbed sound signal () are distributed in several predetermined measuring positions () in the acoustic space (), the secondary sound reproduction sources () are distributed in several predetermined correcting positions () in the acoustic space (), the resonance attenuating means is coupled with means for processing the signal to be reproduced () and the electric signal processing means () includes at least one signal controlling means () connected to each means for measuring the perturbed sound signal ().
