The study investigates choir rehearsal room physical and acoustical parameters. The
reverberation time measurements (T30) were carried out in twenty choir rehearsal
rooms. The measurements were provided according to ISO 3382-1:2009. Based on
acquired T30 and room volume, the lower and upper limits of T30 and sound strength G
were estimated (ISO 23591, 2021). Six out of 20 rehearsal rooms had T30 sufficient for
requirements specified for quiet acoustic music. T30 and sound strength G values
allowed us/me to model the optimal acoustical environment for choir rehearsals
according to the number of singers and choir type.
