Acoustic variations with source position and intelligibility

Cultural and religious practices have evolved over the history of Notre-Dame. In the medieval period, the activities of the religious chapter primarily took place within the enclosure of the chancel while in contemporary times the religious use of the building has expanded into the nave. In this line of research, we are investigating how the cathedral effects speech intelligibility throughout the building. In particular, we are interested in how speaking from different locations within the cathedral privilege certain areas of the building. For example, intelligibility is higher in the central nave of the cathedral from the nave pulpit than if the preacher were located within the chancel.
