Sound field in several theatres of cádiz, before and after its restoration

Abstract

In order to recover the historical and architectural heritage in our region, the Andalusian Goverment is carrying out since recent times a quite interesting an important project called "Rehabilitation Plan of Theaters in Andalusia". This ambitious project, still running, includes the rehabilitation of more than thirty andalusian theaters, and inside it we are playing the role of "acoustic consultors" at the request of the region administration. Five of these theaters belonging to the the Cadiz's province has been already rehabilitated and reopened for different uses. They are: Manuel de Falla Theater, in Cadiz, Villamarta Theater in Jerez de la Frontera, Principal Theater in Puerto Real, Olivares-Veas Theater in Arcos de la Frontera, de las Cortes Theater, in San Fernando. They are characterised because they cover a quite wide range ofvolumes (scene excluded), oscillating between 790 m3, in Olivares-Veas Theater, and 81 14 m3, in Manuel de Falla Theater, and seats that oscillate between 221, in Olivares- Veas Theater, and 122 1, in Villamarta Theater. This paper will be devoted to show the results, experimental and modelled, obtained for severals room acoustic parameters, before and after the perfomed restoration in the five theaters previously mentioned. These results will be discussed according to the diferent uses foreseen for these theaters and consequently the success of the restoration perfomed in them will be evaluated fiom the acoustical point of view.
