Download Automated Equalization for Room Resonance Suppression
Estimating room resonances in locations of big events and looking for counter-measures are normally done by sound engineers, mainly before the beginning of the event. In this paper an automation to enhance the audio quality in event rooms by suppressing the room resonances with a parametric equalizer of several high-Q peak filters is proposed. The room characteristics can be identified with few measurements in the listening area during the event, without applying an additional measuring signal (using its original sound signal). Based on this room characteristics the equalization filters are automatically designed. The results of several rooms tested with the automated equalization for room resonance suppression are presented as well as a discussion on the covered topics.
