The investigations involved six contemporary churches: three buildings with a truss type ceiling and three buildings with a reinforced concrete ceiling. The results reveal that in churches with a truss type ceiling, acoustic parameters reach values close to recommendations. In contrast, churches with a concrete ceiling create very unfavourable acoustic conditions. The investigations rendered it possible to calculate the sound absorption coefficient α for the truss type cover.}, type={Technical Notes}, title={The Study of the Influence of the Ceiling Structure on Acoustics in Contemporary Churches}, URL={http://www.czasopisma.pan.pl/Content/110271/PDF/aoa.2019.126363.pdf}, doi={10.24425/aoa.2019.126363}, keywords={church acoustics, reverberation time in the church, contemporary church, church architecture}, }
