Abstract

This paper describes the acoustic evaluation of historical baroque church in Brazil - Igreja Nossa Senhora do Rosário de São Benedito (Church of Our Ladyof the Rosaryof St. Benedict), built in the 18th century. The evaluation was performed in three stages: 1) in situ measurements of reverberation time (RT), early decay time (EDT), definition (D50) and clarity (C80); 2) reproduction of field conditions in a computational simulation using ODEON room acoustics prediction software, and 3) statistical analysis of the data. The integrated impulse response method was used here, as recommended by the ISO/3382-1:2009 standard. Results were subjected to an analysis of variance (ANOVA) to test the accuracy of the model. The model can be considered accurate, especially as far as reverberation times are concerned.
