Abstract

Buluş kapsamındaki yöntem, bir ses sitemindeki ses kaynağının ölçüm merkezine veya en az bir sensöre olan mesafesini yada ölçüm merkezine veya en az bir sensöre göre konumunu hesaplayıp, hesaplanan mesafe yada konum bilgisi ve önceden hazırlanmış olan veritabanındaki algılanan sinyal cevabı verilerini kullanarak ses kaynağının açısal pozisyonunu tepit etmektedir. Bahsedilen veritabanı bilinen ses kaynağı için daha önce yapılmış olan testler sonucunda elde edilen algılanan sinyal cevabı verilerini, bahsedilen test sürecinde kullanılan mesafeleri ve bu bilgilere denk düşen ses kaynağının açısal pozisyon bilgilerini içermektedir. Bu yöntem sayesinde, bahsedilen ses sistemini oluşturan ses kaynaklarının açısal pozisyonlarının tam olarak tespit edilmesi sağlanmaktadır. Bu yöntem, ses sisteminin ses kalitesini arttırmak için yapılacak olan işlemler için temel oluşturmakta ve buluş kapsamındaki ses kaynağının açısal pozisyonunun tespiti sayesinde, ses sistemi elemanlarının gerçek yönlerinin tespiti ile ses yayılım alanında ses sistemi tarafından tam bir hakimiyet mümkün kılınmaktadır.The method according to the invention calculates the distance of the sound source in a sound system to the measuring center or at least one sensor, or calculates the position of the sound source relative to the measuring center or at least one sensor, and determines the angular position of the sound source using the calculated distance or position information and the detected signal response data in the previously prepared database. It is. Said database includes the perceived signal response data obtained from previous tests for the known sound source, the distances used in said test process, and the angular position information of the corresponding sound source. With this method, it is provided to determine the exact angular positions of the sound sources constituting said sound system. This method provides the basis for operations to improve the sound quality of the sound system and, thanks to the determination of the angular position of the sound source according to the invention, a full control of the sound system in the sound propagation field is made possible by determining the real aspects of the sound system elements.
