Resumen
This thesis takes the Teatro Principal Valencia as a sample of study and raises questions to deepen the awareness of its history, architecture and acoustics. Our final objective has been to analyse and reconstruct the acoustic conditions of our theatre in different historical moments, providing a new way of approaching the Valencian architectural heritage with it. In addition to this, we intend to show the potentiality of our current tools of acoustic simulation and auralisation for the study of the most widely deployed theatrical architectural typology in Europe in the seventeenth century: Italian baroque theatre.
The Teatro Principal Valencia is a representative example of an Italian-style theatre because of meeting each and every formal characteristic that define this building typology. Inaugurated in the year 1832, it is the oldest theatre in Valencia and one of Spain’s oldest Italian-style venues, prior even to pioneer projects of the Teatro Real de Madrid (1850), and the Gran Teatre del Liceu de Barcelona (1847).
We have carried out archive research data, the screening of press, bibliographical research, as well as document consultation and compilation, planimetry and images (many of them unpublished), which have made the recovery of the history of the Valencian theatrical venue possible, blurred with the passing of time. This detailed historical study of our theatre has allowed us to select five moments in which its morphological differences could manifest changes in its acoustics: 1832, 1859, 1928, 1968, and 2015.
Normalised acoustic measures have been carried out in the Teatro Principal, and we have developed threedimensional computer models of the five selected morphologies. The current acoustic model has been adjusted with measures on-site. From the aforementioned model, volumetric, geometric measurements and absorption and/ or diffusion coefficients have been introduced with the object of virtually revert each architectural intervention that our theatre has experienced, always basing ourselves on documented historical criteria. All of this has allowed us to rebuild the sonic history of the Teatro Principal Valencia, being able to compare the changes that its acoustic parameters have experienced in more than 180 years of its life.
As a key outcome to this thesis, the geometrical model of the Teatro Principal has been studied thoroughly on its graphics realism through the use of texturisation techniques and virtual photorealistic rendering, achieving a model that can experiment on auralisations in immersive graphic environments (CAVE, PowerWall, etc.), opening the door to new lines of research.
