A Novel Approach for Prototype Extraction in a Multipoint Equalization Procedure

Document Thumbnail

Multipoint equalization is a useful procedure used to enlarge the zone to be equalized in sound reproduction systems by measuring the room impulse responses in multiple locations and deriving a prototype function capable to represent the real environment. This paper deals with the introduction of a novel prototype function derived from the combination of quasi-anechoic impulse responses with the impulse responses recorded in the real environment to be equalized. This is motivated by the fact that at mid and high frequencies the timbre perception and localization is dominated by the direct sound, thus, the measurable, but mostly inaudible magnitude deviations due to reflections should not be equalized. Several experiments have been conducted in order to validate the proposed approach, considering a real environment and reporting objective and subjective measurements in comparison with the state of the art.
