Özet:

From past to present, performance spaces are being designed in order to provide better listening conditions according to their function. Rooms for classical music have different qualities in comparison to rooms for speech, for instance. However, while acoustic design regarding western-originated performances have been present for centuries, no such attempt has been made for Turkish classical music (TCM). This study aims to search for possible acoustic conditions that would complement the characteristics of TCM and try to improve the overall quality of spaces where TCM may be performed. After an in depth analysis of room acoustics parameters, acoustic evaluation systems and characteristics of TCM, spectral analyses are done for western classical music, opera and TCM, in order to understand the distinctions between the three. Afterwards, three different performance spaces with different qualities are modelled digitally in the 3D environment which were then transferred into Odeon room acoustics software, where anechoic audio recordings of TCM are auralised. A listening test is made with the auralisations for the correlation of objective and subjective acoustic parameters, and an acoustic evaluation survey is conducted to the listeners. Afterwards, a virtual room is modelled with conditions close to an anechoic room, where various changes are made in order to achieve better conditions for TCM through trial and error. Finally, four alternatives with the best conditions are taken into a listening test. The results are believed to yield close-to-optimum acoustic conditions for TCM, and may be used for in depth future studies.
