Abstract (EN): Acoustic Silence, Acoustic Intelligibility and Acoustic Sacred Factor are the acoustically constituted determinants of tranquillity in a Catholic church. The results presented here are part of a study that investigates the behaviour of derived acoustic parameters in worship spaces. Acoustically, Silence Factor (SiF) is found to decay quadratically with L Aeq (R 2=0.95, p<0.01); Intelligibility Factor (InF) decays quadratically with mid-frequency Loudness G MF (R 2=0.69, p<0.01) and the prediction of Sacred Factor is found to be insignificant. Architecturally, Silence Factor is found to grow linearly with the width of the nave (of the church) (R 2=0.69, p=0.04), Intelligibility Factor grows linearly with the minimum height of the nave (H MIN-NV) (of the church) (R 2=0.91, p<0.01) and the regression of Sacred Factor is found to be insignificant with the dimensional parameters. The prediction equations presented here could enable a more scientific approach to design and conservation of worship space.
