REMEDIAL ACOUSTICS OF A MONUMENTAL NEOCLASSICAL AUDITORIUM AT TECH. UNIV. ATHENS

摘要

This paper refers to the multipurpose auditorium, namely "Kaftantzoglou" hall, of the School of Architecture of the Tech. Univ. Athens. This hall is housed in a monumental neoclassical building, and it is a Europa Nostra award winner of year 2012 (Fig. 1,2, Table 1). The auditorium is mainly used for lectures, as well as for a variety of functions of the School, and is visited every year by wide range of local and international guests, amongst who, academics, architects, engineers etc. Despite splendor, comfort is severely impaired in the auditorium by poor intelligibility of speech; the latter is associated with excessive subjective reverberation, poor loudness of speech signal in the audience area, perception of detrimental echoes, etc. According to a joking comment, the auditorium could be useful, only as a comprehensive educational paradigm of "what not to do".
