However, due to several reasons like acoustic control, appropriate natural lighting, we can say that the education provided in historic and local buildings were more productive. From the acoustic comfort perspective which is the subject of this study; a significant difference is observed. Even though it is hard to maintain the same factors as these historic and local buildings in today’s world, if we analyze them properly we can have new recommendations, proposals. This study is made to analyze the designs to provide acoustic comfort and suggest precautions that can be taken in today’s school building. To achieve this,
