Abstract
The purpose of this study was to explore the effect of two different rooms (choir rehearsal room, performance hall) on acoustical (LTAS, one-third octave bands) and perceptual (singer [N = 11] survey, listener [N = 33] survey, Pitch Analyzer 2.1) measures of soprano, alto, tenor, and bass (SATB) choir sound. Primary findings of this investigation indicated: (a) significant differences in spectral energy comparisons of choir sound between rooms, (b) choristers' perceptions of hearing and monitoring their own voices differed significantly depending on room, (c) most choristers (82%) perceived that the choir performed best within the Performance Hall, (d) perceived pitch of selected sung vowels within recordings differed significantly based on room conditions, (e) 97% of listeners perceived a difference in choir sound between room recordings, and (f) most listeners (91%) indicated preference for the Rehearsal Room recording
