ABSTRACT:

The choir is a space that greatly influences the design and architectural configuration of a cathedral. Cultural influence, the reform of the liturgy and agreements reached during ecclesiastical councils in the last centuries have promoted a relocation of this space. Since its origins, it has been a privileged and reserved enclosure, providing a private character. This space is reserved for the clergy for prayer, preaching, or chant, promoting churches as places where music can be heard. The Renaissance cathedral of Granada in Spain is one of the most important historic religious spaces in southern Europe. Over time, the choir was moved up from the central nave to the back of the presbytery to be finally distributed inside the cathedral. Virtual modelling using geometrical acoustic prediction is a very helpful tool to investigate these choir locations in the acoustic behaviour of the cathedral. Hence, based on experimental acoustic measurements carried out previously, sound space reconstruction was recreated virtually. The creation of a virtual model of its sound field led to the implementation of the three main documented changes. In this paper, the role of the choir within the liturgy was considered in terms of acoustics and the acoustical performance of the evolution of various interventions was analysed. The impact of the relocation of choral space is evaluated from a perspective that analyses the relationship between subjective qualities and the acoustic parameters measured. In addition, the acoustical suitability of the cathedral in terms of the performance of different music motifs is also considered. Therefore, a comparative analysis in terms of temporal design, incorporating the study of early reflections together with the type of music is addressed to investigate the influence on the acoustical performance of the cathedral
