The article describes a method for automated selection of sound energy absorption coefficients of different materials. The method provides means to calibrate inner space models in software systems that simulate acoustic properties on the example of the Catt-Acoustic system. The reflection of the sound in a synagogue has been investigated and ways to reduce it have been proposed to improve the language comprehensibility index.
