| Descripción: |
Over the last twenty years, many subjectively relevant objective room-acoustics quantities or indicators for evaluating the acoustical quality of an enclosure have been introduced. Whilst indicators give new insight into the acoustical goodness of a receiver position, there is still a need to quantitatively establish the extent that they are influenced by the interior physical features of the enclosure. The relationship between objective room-acoustic indicators and details of enclosure design from the point view of cause and effect are not fully understood; in order to contribute knowledge in this area, quality indicators must be obtained with directional information. A PC based multiple channel measurement system under current development and designed to meet these demands is presented. The system involves software developments together with hardware interfacing. Its potential is discussed and example results are given 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. |
