Validation of the computational model for the archaeoacoustic analysis of the Metropolitan Cathedral of Campinas, Brazil.

Archaeological studies from an acoustic perspective have been used to understand the acoustic behavior of ancient buildings from different historical periods. In this context, this research seeks to validate the Metropolitan Cathedral of Campinas using computer acoustic simulation. Inaugurated in 1883, the building is part of the historical, architectural, religious, and cultural heritage of Campinas-SP, Brazil. Understanding the acoustic quality of the Cathedral at its current stage allows us to analyze its acoustic behavior in the 1923 and 1954 interventions, as well as its original form. To conduct the research, on-site measurements of acoustic parameters and a survey of the physical characteristics of the current configuration were taken. The historical study of space since its construction will make it possible to create virtual models of the church's previous architectural phases that will be used in the acoustic simulation and auralization of all phases. Validation was conducted by comparing the results of the acoustic parameter, the reverberation time of the environment by acoustic simulation with the Odeon software, and the results of the acoustic measurements carried out on site. Validating the model is a crucial stage and an important tool for understanding the acoustic behavior of space throughout its history.
