Résumé

Au cours des vingt dernières années, on a introduit plusieurs quantités objectives subjectivement pertinentes ou paramètres pour l’évaluation de la qualité acoustique d’une enceinte. Bien que ces paramètres donnent des significations nouvelles à la qualité acoustique d‘une position d'écoute, on éprouvé qu’en même le beison d’établir quantitativement le degré de l’influence exercée sur eux par les caractéristiques physiques intérieures de l’enceinte. La relation causale entre les paramètres acoustiques objectives et les détails de conception des enceintes ne sont pas encore complètement compris; on doit obtenir des paramètres de qualité contenant de l’information directionnelle pour l’éclaircir. A fin de répondre à cette demande, on apporte une contribution originelle en utilisant un système de mesure multicanal basé sur ordinateur personnel. Le système comprend des développements de logiciel ainsi que d’interface. On explore le potentiel du système et on en donne des exemples.
