This paper discusses in situ measurements of the speech intelligibility of classrooms in a private university in Jakarta. Seven classrooms with and without stepping students seating area are evaluated. Impulse Response method is used to measure the acoustics condition of the classrooms. Their speech intelligibility level is determined using the reverberation times (T30) and definition (D50) conditions. Results show that all the classrooms have a low frequency reverberation problem. These problems lead to lower their Speech Intelligibility Level. It is also shown that stepping student seating area does not increase speech intelligibility level.
