Raumakustische Verbesserung des Budapester Stadttheaters
The acoustics of the above theatre were assessed by extensive measurements, and methods of room-acoustics employed to gain an improvement. Owing to the short reverberation time absorbent materials could not be used. To increase the sound energy a new wood-lined proscenium was built and wooden panelling also used in other parts of the building. To avoid echoes and interference effects diffusing surfaces were employed. New measurements show that the acoustics were considerably improved. Echoes and interference effects were totally suppressed and the sound energy appreciably increased. The reverberation time was increased and its frequency curve improved as a result of boosting at higher frequencies.
