Effects of a Straw Phonation Protocol on Acoustic and Perceptual Measures of an SATB Chorus

Recent scholarship has suggested that semi-occluded vocal tract (SOVT) exercises may increase vocal economy of individuals by reducing vocal effort while maintaining or increasing acoustic output. Choral singers, however, may use different resonance techniques or change voicing behaviors in an effort to hear their own sound in relation to others. One investigation revealed significant increases in a choir's mean spectral energy after participating in a straw phonation protocol. However, that study reported only acoustic measures and did not include choristers' perceptions of the choral sound and their own voicing efficiency.
