Subwoofers in Rooms: Experimental Modal Analysis

Authors: Backman, Juha

AES Convention 128 · Paper 7970 · May 2010

Abstract

The behavior of a loudspeaker in a room depends fully on the coupling of the loudspeaker to the room modes, which are in the subwoofer frequency range individually identifiable. The modes can be determined through computational methods if the surface properties and room geometry are simple enough, but systems with complex properties have to be analyzed experimentally. The paper describes the use of modal analysis techniques, usually applied only to two-dimensional structures, for three-dimensional spaces to determine experimentally the actual modes and their properties.
