Abstract
The purpose of this study was to examine the possible change in acoustic measures of collegiate choir singers after rehearsals of different lengths (50-, 80-, 110-minute), and through testing after four fifteen-minute resting periods to determine the level of voice rebound within an hour after the rehearsal was complete. Spoken and sung acoustic measures of 30 collegiate choir singers’ voices were recorded before and after prolonged singing in a 50-, 80-, or 110-minute choir rehearsal. For one hour immediately following the rehearsal, the same acoustic measures were recorded at fifteen-minute intervals for a total of four post-rehearsal tests. This data was analyzed as a whole and through the between-subjects factors of rehearsal length, participants’ self-reported percent of rehearsal time sang, amount of singing prior to rehearsal, and voice type. Results showed participants’ spoken and sung energy output (MSE, SER, MaxE, MinE, and ER), sung and spoken pitch range (MaxP, PR, and MSF0), and maximum phonation time were most notably affected by the vocal loading during choral rehearsal. Evidence of voice rebound was seen for MSF0, MSE, MaxP, and PR after 60-minutes of vocal rest.
