The Observatoire de la qualité de l’air intérieur (OQAI, Indoor Air Quality Observatory) started in 2013 a national campaign on 300 schools located in France. Measurements and questionnaire-based investigations are performed in order to evaluate exposure level to air pollutants. In addition visual, thermal and acoustic comfort is also considered. The acoustic comfort evaluation is based on the teacher and investigator responses to different questionnaires and also exposure acoustic measurements in the classrooms. On a limited number of schools standard building acoustics measurements were carried out to determine the acoustic performance (airborne and impact sound insulation, reverberation, speech intelligibility, etc.). A method is proposed for evaluating the acoustic performance based on the description of classrooms’ characteristics in the studied schools and applied to about 100 schools for which completed questionnaires and acoustic recordings were available. The results from acoustic performance prediction are studied with respect to regulation levels. Furthermore, these predicted results are compared to responses from the teacher questionnaire to evaluate the relationships between building acoustic characteristics, noise exposure and perceived comfort. This comparison provides a first overview of the acoustic environment in classrooms.
