Acoustic evaluation of three architectural types of religious buildings in Zlín

The acoustics of religious buildings represents one of the most complex cases of architectural acoustics. This is especially due to the fact that the different liturgical functions require other listening requirements. More specifically, in churches, there is often acoustical design conflict between the intelligibility of the spoken word and conditions for enjoyment of music. These spaces can be evaluated by objective or subjective parameters of the acoustic quality of listening positions. This article focuses on the evaluation the reverberation time, as well as the spatial and directional distribution of the acoustic energy of three churches in Zlin, which are distinguished by the time of construction, the architectural style and the building structure. © 2018 Studio D - akustika s. r. o.Ministry of Education, Youth and Sports of the Czech Republic within the National Sustainability Programme [LO1303 (MSMT-7778/2014)]; European Regional Development Fund under the project CEBIA-Tech [CZ.1.05/2.1.00/03.0089]; Internal Grant Agency of Tomas Bata University in Zlin [IGA/CebiaTech/2018/001
