Summary:
The church of San Luis de los Franceses, Seville, Spain, from the 18th century, represents one of the most impressive examples of the Spanish baroque architecture of the master Leonardo de Figueroa. The singularity of its Greek cross plan, in relation to other churches of the master himself and the contemporaries in the city of Seville, contradicts the Spanish tradition of rectangular plan and suggest possible guidelines provided by the Society of Jesus. It highlights the great dome that is almost exempt. In this communication, the description of the sound behaviour of the church is presented based on the main acoustic parameters. For this, the location of the sources is considered in four positions, in order to analyse the different configurations that, as a consequence of its uses throughout history, it has had and currently has: Main altar, side altar, choir and Dome. The church with a high reverberation time, gives rise to different subjective sensations of reverberation depending on the sound source location used. This fact is reflected in most acoustic parameters analysed. The desacralized of the site has now led to the use of the church as a multipurpose room, which collects different performing’s where the word and music have special importance. Of special relevance are the events where the sound source is located under the dome, with the audience located around it. The behaviour of this source is analysed, due to the acoustic complexity implicit in this type of surfaces. To do this, the possibility of finding double slopes has been studied and the dome behaves as a coupled space. The analysis of the impulse responses was carried out by means of Bayesian parameter estimation.
