Avaliação do desempenho acústico das salas de aula do bloco 600 do Instituto Federal de Goiás, Campus Formosa: um estudo de caso.

Abstract

This work proposed the analysis of the acoustic characteristics of the classrooms and the circulation corridors of the block 600 of the Instituto Federal de Educação, Campus Formosa. The place serves to carry out the classes of the bachelor's degree in civil engineering and of the technical course in the EJA modality in buildings, being a shed equipped with laboratories and rooms with unique characteristics in relation to the rest of the institution, couting with drywall walls and rooms in very different sizes, which generated a lot of interest in knowing their current acoustic conditions. Being aware of the romm’s characteristics makes it possible to assess acoustic comfort, possible impairments in the understanding of the teacher's speech and disorders that interfere with the students' attention. Consequently, the present work aimed to collect the acoustic parameters of equivalent sound pressure levels and reverberation time characteristic of the object of study. The methods described in the NBR 10152 (2017) standards were used to measure the equivalent sound pressure levels of each room and corridors using the decibel meter and NBR 12179 (1992) to calculate the reverberation time using the Sabine or Eyring formula. With the survey of these parameters, it was possible to compare them with the standardized reference values and classify the acoustic performance of the rooms, reaching the conclusion that the environments are not suitable for the intended use. A possible solution and indications for possible improvements of the rooms in a more significant and efficient way were raised.
