The “Real Teatro di Corte” of “Reggia di Caserta”. Spatial sound propagation

The court royal theatre of Caserta is part of the construction complex called Reggia, a palace that has been commissioned by the King of Naples Charles III. This important architecture, considered a cultural heritage site protected by the United Nations Educational, Scientific and Cultural Organization (UNESCO), has been studied by the authors in such a way that the main acoustic parameters outlined in ISO 3382-1 are herein represented in combination with some shots of the impulse response (IR) recorded during the survey. As an alternative way of extending the acoustic study of any room, this methodology is recommended for understanding the construction elements that contribute to the early and late reflections when the volume in discussion is very elaborated as an Opera theatre. A brief overview of the historical background of this marvelous architecture is also given.
