RESUMO:

Schools are places of learning in which communication is essential for the fulfillment of their function, but most Brazilian schools do not have adequate acoustic conditions. When the spoken message is not clearly heard by the students, the understanding of the speech is affected and, consequently, the learning process is impaired. Good acoustic conditions in classrooms make the learning process easier and less stressful for teachers and students. The resources invested in improvement, in order to promote acoustic comfort, are still seen only as expenses and not as investment in education. The research question raised is: do the classrooms of federal higher education institutions in Natal/RN have adequate architectural acoustics? The main objective of this study is to evaluate the acoustic quality of theoretical classrooms in federal institutions of higher education in Natal, where one or more classroom models are replicated throughout the institution, aiming to propose guidelines for such classrooms with regard to acoustic conditioning. Acoustic parameters were found for this type of research, such as Reverberation Time (T20), Initial Decision Time (EDT) and Speech Transmission Index (ITS), as well as other important controls for speech intelligibility analysis. The methodological procedures consist of the bibliographic research on the subject, as well as the application of field research, in order to ascertain a true acoustic quality of the classrooms studied and to make possible solutions proposals. Acoustic measurements were performed in the classrooms of the Federal Institute of Rio Grande do Norte and the Federal University of Rio Grande do Norte, where low acoustic quality was found in all classroom standards. From this, we proposed to improve the acoustic quality of the rooms, finding that 50% of area of absorbent material in the lining significantly improves the acoustic conditioning of the room for speech, with better results with 100% of the area of liner material in absorbent and more homogeneous distribution of parameters throughout the room when absorbent material is added to 25% of the posterior wall area. In addition, we found better results in the classroom with a width greater than the depth, among the analyzed rooms.
