The quality of educational activities strongly depends of the acoustic conditions of classrooms. This article presents an evaluation of two theoretical methods of calculation of the Reverberation Time (RT) in classrooms, based on the formula of Sabine and Hohmann, Setzer and Wehling. This study was carried out in classrooms of the Federal University of the Paraná (UFPR), located in Campus III, Sector of Technology, Block IV, located in the city of Curitiba, Brazil. RT measurements have been made in situ, aiming to corroborate the results obtained form the application of formula,. The results indicate that the modified formulae of Sabine (Indirect Method) is the most suitable one, since the calculated value are the closest ones to the measured reverberation values.Downloads
