In the restoration of historical buildings, the
characteristics of the original period and the design decisions of the original
period should be preserved. The rich interior volumes of historical buildings
should not be reduced, the original ceiling height should not be changed and
their original interior forms should be conserved. In addition, the
requirements of current standards in the restoration of historical buildings
should be met as much as possible. Providing auditory comfort conditions is
also one of the important parameters in the restoration process. In this study,
the meeting room in the historical building was analysed, the design decisions
of the original period of the meeting room were preserved, and an acoustic
improvement project was presented depending on the characteristics of the
historical building. In the acoustic project proposal, the original room
height, the richness of the interior volume, and the perception of the mirrored
vault system were preserved to maintain original period design decisions. In
the acoustic project proposal, auditory comfort conditions were improved by
increasing the total absorption rate in the meeting room. Reverberation time
analyses and delayed reflection analyses were performed. In addition, the
homogeneous propagation of the sound in the space was examined by using the
acoustic simulation program. With the acoustic project proposal, the
reverberation time was controlled in line with the DIN18041 standard, the
delayed reflections were greatly reduced, the homogeneous propagation of the
sound in the space has been improved, and the intelligibility of speech in the
meeting room has been increased.
