Çok Amaçlı Alev Alatlı Konferans Salonunun Akustik Parametrelerinin Ölçülmesi

Öz

Çok amaçlı salonlar, konferanslardan konserlere, tiyatro gösterilerinden spor etkinliklerine kadar çok çeşitli etkinlikler için kullanılmaktadır. Bu tür salonların akustik performansı, etkinliğin türüne, sıcaklık değişimlerine ve salonun doluluk oranına bağlı olarak büyük ölçüde değişebilir. Bu nedenle, çok amaçlı bir salonun akustik özelliklerinin belirlenmesi, mekânın her kullanım senaryosunda en iyi akustik performansı sağlayabilmesini sağlamak için kritik öneme sahiptir. Çok amaçlı bir konferans salonunda 2 farklı uyaran ve 2 farklı sıcaklıkta bir ölçüm araştırması gerçekleştirilmiştir. Salonun tepkisi, çok yönlü mikrofonlar ve bir yapay kafa kullanılarak 10 alıcı konumunda kaydedilmiştir. Ham veri işlenerek yankılanma süresi, erken sönümlenme süresi, bas oranı, merkez süresi, netlik, tanımlama, hızlı konuşma iletim indeksi ve işitsel çapraz korelasyon elde edilmiştir. Akustik performansı değerlendirmek için sonuçlar ilgili standartlar ve literatürle karşılaştırılmıştır.

Measurement of Acoustic Parameters of the Multipurpose Alev Alatlı Conference Hall

Öz

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.
