MODIFYING LOW FREQUENCY ROOM ACOUSTICS 1: LOCAL ACTIVE DE-REVERBERATION
M. R. Avis, Paul Darlington · 2024
The low frequency modes of small rooms introduce undesirable coloration to sound reproduced within them.This paper describes methods to remove this coloration by actively cancelling the reverberant eld at a listening position -a process which has been termed dereverberation.The control achieved is local to the designated listening point and fails at atherpoints within the space.The volume over which acceptable tie-reverberation is achieved is demonstrated to be in uenced by the mode shapes, by source positionng relative to the mode shapes and by equency.
