There is a lot of acoustic researches made for Roman Catholic churches and because of differences in traditions and culture comparing to Orthodoxy, this is not the best idea to use its acoustic estimators for Orthodox churches. The article shows results of measurements in exemplary Orthodox churches in Poland and proposal of psychoacoustic tests using convolution technique, which would allow to formulate the new acoustic outlines for Orthodox churches. The researches were made especially considering choral music, which is inseparable part for East Christians culture, so as a test sounds, there were Orthodox choir sound samples recorded in anechoic chamber convoluted with impulse response of measured churches.
