Lecture Halls - Room Acoustics and Sound Reinforcement Kurt Eggenschwiler Empa Materials Science & Technology, Laboratory of Acoustics CH-8600 Duebendorf, Switzerland, e-mail: This paper describes our experience with lecture halls with regard to the room acoustics, sound reinforce- ment and audio frequency induction loops for persons with hearing impairment. The optimum reverbera- tion time and geometrical conditions for classrooms are well known.
