This master thesis analyses the acoustics in school buildings, using the example of the European elementary school 'Dr. Leopold Zechner' and the annex school building for visually handycapped children in Vienna in the 15th district. The fi rst chapter describes the development of school buildings from the 19th century until today, implying the subject of the acoustics. In addition to that, the focus is held to the physical and mental infl uences which can result from bad room acoustics in schools. The following chapter defi nes fundamental physical defi nition of room acoustics and presents the current state of the acoustic development of school buildings. In addition to that, acoustic measurements are realized and analysed in the example school. The fi nal part provides a small insight in possible innovative arrangements for improving the acoustics in school buildings, with the aid of two new example schools.
