The acoustic conditions of classrooms received a lot of attention in the last decades because of their essential role to guarantee effective teaching and learning, especially at the baseline levels of the educational path. Most classrooms in Italy, of every grade and type, do not meet the minimum acoustic requirements for make them fit for their function since until now the laws were obsolete, therefore not in line with the most updated international standards or too often not observed. The purpose of this work is to provide a tool to ensure the acoustic quality of the classrooms for a better teaching-learning process.
