Resumen de Acoustically coupled volumes in the cathedrals of Murcia and Seville
Teófilo Zamarreño García, Jorge Delgado Aguilera, Sara Girón Borrero, Francesco Martellotta
Cathedrals are complex monuments built through the repetition of volumes separated by arches, vaults, and columns, in addition to a great variety of lateral chapels. In the so-called "Spanish mode" the choir is situated in the centre of the main nave and generally constitutes a more absorbent volume connected by an acoustically transparent opening with the rest of the cathedral.
This space, together with the lateral chapels, can present the phenomenon of acoustic coupling.
In this work, as a manifestation of this coupling, an analysis is performed, by means of standardised parameters and through the application of Bayesian methods, on the non-linearity of the energy decay curves of the impulse responses registered in situ in the Vélez Chapel of the Cathedral of Murcia, the Royal Chapel of the Cathedral of Seville, and in their respective choirs.
