Acoustic investigations of the contemporary churches in Poznań

Sygulska A.

Vibrations in Physical Systems

2014

Vol. 26

281--288

The paper discusses acoustic issues of contemporary churches. Church interiors should be designed so as to obtain intelligibility of speech and simultaneously take organ music into account. It is a tough task as acoustic parameters required for speech and organ music are entirely different. Analysis of the issue was carried out on the basis of investigations in five contemporary churches in Poznań. In total, seven interiors were investigated as two of the churches were two-storeyed. The acoustic investigations were conducted by means of an omnidirectional sound source, a SVAN 945A Sound Level Meter and the DIRAC programme. RT, Ts, C80 and C50 were measured. The acoustic parameters were compared with values recommended for churches. The investigations allowed to draw clear conclusions concerning the influence of architecture of the interior on acoustic parameters.

Acoustic study of two modern churches

Vibrations in Physical Systems

Vol. 25

381--386

The acoustics of churches is a very important issue, especially because of the speech intelligibility. This aspect is very often neglected during the designing process in modern sacral architecture. Too long reverberation time and acoustic defects such as echo result in the lack of verbal intelligibility. Two modern churches were investigated in this paper. Acoustic parameters were measured and analyzed in terms of their function. The results of the measurements in the objects were compared and analyzed in terms of the influence of the architecture on the acoustics. The results of the measurements show considerable differences in acoustic parameters in both churches.
