The architecture looks for the best relation between humans and the built spaces, mainly when the cases are about rooms whom the user spents the most time of day, like in the schools. The teaching-learning process is related to the speech intelligibility, to the communication between students and teachers, moreover, related to the student’s concentration and attention skills, that contribute to their cogninitive development.

For this, important parameters that are considered relevant for this research were measured, like the Sound Pressure Level (SPL), Reverberation Time (RT) and background noise. The methodologicals procedures consisted, in short, in the qualitative and quantitative diagnosis from the school, looking for an avaliation of the acoustic conditions for a future intervention including acoustic isolation and conditioning through a prelimininary study in project. By the way, acoustics guidelines were listed for projects in the school and, for the subject research in analysis, new materials and visual identity were proposed, then, bringing more quality for the classrooms. The research confirms the importance of include the acoustics like a overriding design conditioning, looking for humanized and confortable areas
