Measurement of Acoustic Parameters of the Multipurpose Alev Alatlı Conference Hall

Multi-purpose halls are used for a wide range of activities, from conferences to concerts, theatre performances to sporting events. The acoustic performance of such halls can vary greatly depending on the type of event, temperature variations and occupancy of the hall. Therefore, determining the acoustic characteristics of a multi-purpose hall is critical to ensure that the venue can provide the best acoustic performance in every usage scenario. A measurement survey is conducted in a multipurpose conference hall through 2 different stimuli and in 2 different temperatures. The response of the hall is recorded at 10 receiver locations using omnidirectional microphones and a dummy head. The reverberation time, early decay time, bass ratio, centre time, clarity, definition, rapid speech transmission index, and inter aural cross correlation are extracted from the raw data. The results are compared to the relevant standards and the literature to evaluate the acoustic performance.
