Optimal Acoustic Reverberation Evaluation of Byzantine Chanting in Churches
نویسندگان
چکیده
Byzantine chants constitute a form of monophonic vocal music characterized by lengthy phrases and by musical scales with intervals smaller than the western music semitones. Byzantine churches have extremely long Reverberation Time and their acoustics is dominated by the contributions of the diffuse sound field. Thus, the sound character of Byzantine chanting is closely linked to the acoustic reverberation. In this work we examine the perceived preference for the various features of reverberation imposed on excerpts of Byzantine psalms. This is achieved by simulations of typical churches with varying internal volume, reverberation time and source / receiver distance, utilizing chants from the DAMASKINOS corpus. The simulation (auralization) results were evaluated via statistical preference method using a group of 15 listeners. The results of such controlled experiments illustrate the listener preferences and acceptability of various parameters or combinations of parameters related to reverberation, e.g. of the Reverberation Time value in relation to church dimensions and listener position inside the

Calligraphy was very important from the beginning in Islamic civilization because of the Rasm of the Holy Quran. The presence and application of the Kufic script, as one of the most common forms of calligraphy in the early Islamic age, with its own visual and conceptual features in the Greek churches and monasteries of the tenth and eleventh centuries (fourth and fifth centuries (AH)) raises ma...
متن کاملAcoustic Study of an Auditorium by the Determination of Reverberation Time and Speech Transmission Index
The quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. This acoustic quality can be characterized based on the reverberation time (RT), speech transmission index (STI) and the sound insulation. In this context, an acoustic study was conducted in an auditorium located in the Higher...
