The aim of this research is to evaluate acoustical quality drawbacks at one type projects for education buildings. For this aim Ankara (for Central Anatolia) and Karabuk (for Black Sea region) regions’ national primary schools are researched according to room acoustics condition and environmental factor. These schools’ projects are compared with some private schools and other cities’ national school projects, and several sounds levels are measured at different critical zones in schools. Researches showed that there are several effected sound sources in schools which sometimes can be incessant, sometimes temporal, and directly affect the indoor noise level. The importance of these levels is, first, at the signal to noise ratio for communication between students, teachers, and other staff. Second, hearing and understanding the loudspeaker in daily period and especially during emergency time is vitally important. At this research, two different critical materials, conditions, and areas are determined; daily and constantly critical zones and critical zones at emergency conditions such as stairs, emergency doors, corridors, elevator indoor, etc. Not only emergency time but also daily period problems which are directly related to the noise level in schools need different solutions for the control of acceptable sound levels according to international standards.
