Abstract

PURPOSE: The aim of this systematic review is to outline the main methodologies used for measuring noise in classrooms and if the noise levels found are suitable standards. METHODS: A survey of articles published in the last ten years, using six different databases. Were verified 1.088 publications and only eight studies met the inclusion criteria: (a) articles published in the last ten years, (b) articles available in full, (c) studies that have measured the noise in the classrooms of regular schools. Data analysis: descriptive analysis was performed of selected publications. RESULTS: Five studies conducted to measure the noise using a sound level meter. One measurement performed using a dosimeter and two studies used a laptop with audio recording software. In all classrooms, the noise level was higher than allowed. CONCLUSION: Classrooms are noisy environment and there is no standardization regarding the methodology that should be used to measure the noise in these places. Therefore, schools need to be guided constantly about the importance of acoustic adaptation in the classroom.
