Abstract

Interior designs of historical buildings should be made in accordance with their original period. Spaces with large volumes should be protected in historical buildings, the volume should not be reduced by making suspended ceilings and rich interior spaces should be preserved. In addition, there are other parameters that are important in the interior design of historical buildings. Comfort conditions of historical places should be provided and comfort conditions should be considered in the design process of historical places. In this context, it is of great importance to obtain auditory comfort conditions, which is one of the indoor comfort conditions. In rooms with large indoor volumes, auditory problems caused by the large volume can often be observed. In particular, the problem of high reverberation time is encountered in rooms with large internal volumes. In rooms used for speech, it is essential to keep the reverberation time under control in order to provide speech intelligibility. In this study, the restoration work carried out without damaging the original period feature of the meeting hall in the building of the Faculty of Science and Letters of Istanbul University was explained, and a design proposal is presented in order to provide auditory comfort conditions. The reverberation time problem that may arise from high ceiling heights was improved by maintaining the original ceiling height without changing the room volume. Accordingly, the total sound absorption rate in the room was increased. Surface coating materials with a high sound absorption coefficient were proposed and it is aimed that the proposed surface coating materials do not damage the original period feature of the historical building. In summary, a design proposal was presented in order to keep the reverberation time of the meeting room in the historical building under control. It is aimed to preserve the original interior forms and richness of the meeting room.
