Hagia Sophia built in 6th century and Süleymaniye Mosque in 16th century are the two major monuments of Istanbul World Heritage Site. Süleymaniye Mosque has always functioned as a mosque, while Hagia Sophia previously functioned as a church and mosque while currently serving as a museum. Their historical significance as of being cultural heritages and religious use in relation to acoustics have motivated many researchers to test and discuss over their interior sound fields. A comprehensive study is necessitated to assess the acoustical conditions of both structures in relation to their architectural features and interior finish materials and to examine the changes occurred in the acoustical comfort levels due to the main repairs underwent their life time. One aim of this study is to discuss over the acoustical field test results held in different periods by comparison of common room acoustics parameters. On the other hand, with their immense scale and multi-domed upper structures both monuments exhibit multi-slope sound energy decay. For that reason, as a step forward relevant acoustical predictors including decay rates are discussed in light of different functional uses and spiritual acoustical needs of such monumental sacred spaces.
