Outline
This auditorium with 1,160 seats was originally built approximately 80 years ago and renovated in 2002. The renovation was required to preserve the original form of this important historical building. Active Field Control(AFC) is installed to transform only the acoustical environment without architectural changes to the room shape, ceiling height, etc.
The AFC system is composed of two systems: A) a lateral reflection control system to compensate for the excessive room width, in which the optimum FIR is simulated by creating a model with an “image wall” and comparing it to the existing model, B) a reverberation control system to increase the reverberation time.
