Vocal health of middle school and high school choral directors.

摘要

Teachers are considered professional voice users because they depend on the regular and uninterrupted use of the voice. The nature of teaching requires more extensive use of the voice than other professions. Therefore, teachers are faced with a greater risk of developing voice problems. In addition to using the voice to present content to students, teachers must also manage the classroom and student behavior. All of these activities have potential to compromise vocal integrity.; The purpose of this study was to examine the vocal health of selected middle school and high school choral directors. Specifically, it explored relationships between vocal health condition as determined by the modified Voice Handicap Index (VHI) and self-report vocal health rating and (a) age, (b) gender, (c) years of teaching, (d) level of teaching, (e) vocal health education, and (f) fundamental frequency and intensity ranges of the voice as indicated by the voice range profile (VRP). This study also sought to determine the relationship between VRP, and age, gender, years of teaching, and level of teaching. Results indicate choral directors' vocal intensity range is significantly smaller than the trained and untrained populations, choral directors' minimum vocal intensity is significantly higher than the trained and untrained populations, and choral directors are able to produce significantly fewer semitones resulting in a smaller vocal frequency range than trained and untrained populations.
