The acoustic conditions of classrooms can directly interfere in the teaching and learning process. Some constructive components can influence in such conditions. In hot-humid climates, openings are used for the main purpose of providing natural ventilation. Conflict situations between the needs of environmental comfort can be verified when such components also allow the entry of external noise, causing a decrease in sound insulation. In addition to aspects related to insulation and ventilation, it is necessary to address the interference of openings in the internal acoustic quality. In this context, the present work aims to evaluate the influence of the size of the openings on the acoustic quality of naturally ventilated classrooms based on the municipal public education network in Maceió-AL. The methodology consisted of parametric analysis, based on the results of acoustic quality parameters: Reverberation Time (TR), Clarity (C50), Speech Transmission Index (STI) and Percentage of Consonant Articulation Loss (%ALCons), obtained through computer simulation. Through the results, it was observed that the increase in the opening area leads to significant improvements in the values of acoustic parameters. Knowledge about the effect of openings on internal acoustic quality can help architectural design in the decision-making process by architects.
