Architectural acoustics in educational environments: a case study of the expansion of Trinta de Outubro School in Lebon Régis, Brazil

Abstract

The article examines the importance of acoustic treatment in schools, focusing on a case study of the Escola Estadual Trinta de Outubro in Lebon Régis, Santa Catarina, Brazil. The institution serves 220 students, with an emphasis on regular education tailored to rural contexts, offering diverse activities that integrate theory with practical and cultural learning. The proposed expansion of the school aims to create additional spaces, such as classrooms, laboratories, and an auditorium, to improve infrastructure and foster interaction with the local community. Objetively, the study presents the acoustic treatments applied to these spaces, highlighting the significance of acoustics in educational environments. The methodology considered theoretical foundations on sound, noise control, regulatory standards for acceptable noise levels, and acoustic insulation methods, as well as acoustic treatment involving reverberation time calculations and the selection of appropriate materials for classrooms, a computer lab, and the auditorium. The acoustic interventions yielded positive results, achieving reverberation times within recommended parameters. The conclusion underscores compliance with normative specifications for acoustic treatment in the studied environments, emphasizing the importance of considering acoustics in the design of educational spaces to enhance the teaching and learning process.
