Examining the Influence of Cumulative Vocal Demands on Singing Performance in Music Students

The various vocal demands imposed on music students over the semester might impact their voice stability and performance. To maximize vocal health in music education, it is critical to understand how these demands influence voice quality. The research aimed to investigate how cumulative vocal demands affected the singing ability of voice majors in music during a semester. Aerodynamic and acoustic voice measurements were utilized to assess singing performance at several points throughout the semester. At these times, each participant was examined individually to detect variances in vocal performance.

Utilizing a time-course design, data was examined using repeated measures and one-way within-participants analysis of variance to evaluate changes over time. Voice quality was evaluated using the wearable voice monitor, aerodynamic testing device, and voice analysis software. Self-reported information on voice problems and usage was also gathered. There were no statistically significant variations in the acoustic and aerodynamic characteristics of the participants' singing performances, even with the prolonged monitoring time.

Based on their self-reported statistics, the students demonstrated a reasonable level of knowledge of voice care and usage throughout the semester.

The research indicates that voice students' singing performance was not significantly affected by the cumulative vocal demands of a semester, with their vocal characteristics remaining constant over time.
