Acoustical analysis of a theatre: Istanbul Metropolitan Municipality Beyoğlu theatre as a case study

This thesis aims to uncover the performance criteria regarding acoustic comfort of theatre halls and the effects of these criteria on sound quality in these halls. As the case, the project, which recieved the first prize from İstanbul Metropolitan Municipality at Beyoğlu Scene quest and to which my thesis supervisor Prof. Dr. Füsun Demirel contributed as the acoustics advisor, is depicted. Among the three halls of the Project, the Grand hall is analyzed using ODEON software in terms of performance criteria regarding reverberation time (RT), early decay time (EDT), clarity (C80), definition (D50), early lateral fraction (LF80), speech transmission index ( STI).
