Index assessment of the acoustics of Orthodox churches in Poland

Acoustic tests conducted in Orthodox churches in Poland together with surveys and geometric measurements, as well as the architectural style along with other distinguishing features, were presented. The obtained results were compared to the subjective tests conducted in advance for the same architectural objects with the index assessment. The proposed index method for determining the single-number assessment was verified in two Orthodox churches from outside Poland in the index values for the geometric models the design stage, is featured.
