Assessment of the Acoustic Performance of Historical Structures That Shed Light on Today's Technologies: Fatih Pasha (Kurşunlu) Mosque - Diyarbakır

Abstract

Today's technologies are produced using new construction methods and new materials and using different techniques. While the time dimension of the parametric design, which is defined as the fourth dimension, is sometimes an hour, day or year, sometimes this is seen as a bridge between the past and the present of the structures that have survived in a large date range. For this reason, the support of new building materials and techniques from time to time with methods that have the technical data of the period obtained as a result of our historical heritage and long experience can provide us with new perspectives. The architectural features and construction techniques of historical mosques contain important data on the acoustic performance of religious buildings. Our heritage knowledge must be blended with new knowledge and technologies. Within the scope of the study, the details and systems that were effective in providing acoustic performance parameters in the architecture of Fatih Pasha (Kurşunlu) Mosque, which was the first Ottoman period work of the city located in Diyarbakır Suriçi area, were examined. Among the objective parameters of the sound, Reverberation Time (RT), Early Decay Time (EDT), Clarity (C80), and Definition (D50) metrics were measured. The obtained data were compared with reference values and analyzed. As a result of the data and analysis obtained in the literature reviews, it was determined that the acoustic values of the mosque were in harmony with the reference values. When the measurement data were compared with the obtained international publications, it has been observed that the sound pressure value ranges depending on the frequency of acceptable indoor acoustics standards. The importance of restoration works in harmony with materials such as basalt, brick, limestone, lime mortar and plaster which are the original materials of the building was highlighted in terms of acoustics.
