Acoustic suitability of heritage-listed buildings using BRASS software: a case study of Armando Gonzaga Theater, Rio de Janeiro, Brazil
* Presenting author
The Armando Gonzaga Theater was designed by one of the greatest modern Brazilian architects, Affonso Eduardo Reidy. Protected by INEPAC (State Institute of Cultural Heritage), this theater is located in the neighborhood of Marechal Hermes, a district of lower purchasing power in the west zone of Rio de Janeiro, far from the city center, and unique cultural facility on the spot. Being a heritage-listed building used for different purposes, from plays to acoustic and amplified concerts, it is necessary to adapt it in order to provide better acoustic performance using the new technologies. However, an intervention project in this building must respect the requirements imposed by INEPAC. The aim of this paper is to study alternatives for acoustic adequacy of this theater that are compatible with the heritage limitations required. The methods used are the simulations of the current situation compared to the measurements in the place, and the simulations of situations with new interventions, using BRASS software (developed in the Urban Engineering Program of the Federal University of Rio de Janeiro). The results show that it is possible to make these proposed adjustments, improving the acoustic performance of the building, but respecting its original characteristics.
