Abstract: In classrooms the speech intelligibility is very important to the development of a good teaching/ learning process. In the intelligibility evaluation are included various acoustic parameters such as reverberation time (RT), initial decay time (EDT), definition (D50), articulation loss of consonants (%ALCons) and speech transmission index (STI). The classrooms of the Faculty of Civil Engineering, Architecture and Urbanism, State University of Campinas have received criticism about the acoustics and is scheduled the acoustic suitability of these rooms. This paper shows the approach and procedures for evaluation, acoustic analysis and suitability of classrooms. In a room prototype were measured the following acoustic parameters: signal- to-noise ratio, reverberation time, background noise, initial decay time, definition, percentage of articulation loss of consonants, speech transmission index and clarity. With these parameters was evaluated the acoustics of the room. The software Dirac (Bruel & Kjaer) was used for measurements. It was effected acoustic simulation of the room with EASE 4.2® software, specifically designed for simulating room acoustics. Through the simulations were studied strategies and economic options for adjusting the room to improve its acoustic characteristics with the best cost benefit.
