Acoustic analysis of selected sacred buildings in Szczecin
Acoustic analysis of selected sacred buildings in Szczecin

Summary/Abstract: The aim of this study was to acoustically assess selected sacred buildings located in Szczecin. The research part contains the research methodology and the results obtained. The research was carried out using two methods. The first one is the integrated impulse response method where, using a bursting balloon, the time of sound pressure drop was measured at selected points of the object. In the second research method, the interrupted noise method, the sound pressure drop was measured after the noise generated by the omnidirectional loudspeaker had ceased. Reverberation time was calculated for the results obtained, which is the main and basic parameter determining the interior acoustics. On the basis of the above-mentioned measurements, the reverberation indicators for the temples were also calculated. When analysing the components of the reverberation indicator, it was noticed that poor acoustics in the sanctuary concerns speech, while interior acoustics is good for the reception of organ music. In the analysed church, the reception of liturgical music is also better than the reception of speech, but the differences between these values are small.
