Description

The main purpose of this study was to consider the effects of amplification and vocal function exercises on the perceived vocal health of elementary music educators (N = 37) from Oklahoma (n = 11) and Texas (n = 26). Participants were assigned to the use of the ChatterVoxTM amplifier or vocal function exercises based on pretest scores on the Voice Handicap Index with Music Teacher Voice Questionnaire (VHI/MVQ). Following the 4-week study period, participants completed the posttest VHI/MVQ. The results of a one-way ANCOVA that used treatment group as the independent variable, the summed posttest scores as the dependent variable, ... continued below

Description

The main purpose of this study was to consider the effects of amplification and vocal function exercises on the perceived vocal health of elementary music educators (N = 37) from Oklahoma (n = 11) and Texas (n = 26). Participants were assigned to the use of the ChatterVoxTM amplifier or vocal function exercises based on pretest scores on the Voice Handicap Index with Music Teacher Voice Questionnaire (VHI/MVQ). Following the 4-week study period, participants completed the posttest VHI/MVQ. The results of a one-way ANCOVA that used treatment group as the independent variable, the summed posttest scores as the dependent variable, and the summed pretest scores as the covariate or control variable indicated that there was a statistically significant difference between the adjusted means for the posttest scores, favoring the exercises group. The overall group and both treatment groups reported frequent loud voice use in work settings and in public places. The overall group and the amplification group reported hoarseness after prolonged talking. The exercises group did not report as great a problem with hoarseness after prolonged talking. Secondary purposes addressed demographic variables. Women perceived greater overall vocal difficulties than men; men frequently reported specific vocal complaints that were not commonly indicated by women. The vocal problems of women may have been associated with loud voice use. The following common vocal complaints of men may have been related to the use of falsetto while teaching: need for vocal rest, worse voices in the evening, dry throats, loss of voice, obvious pitch breaks in their singing voices, pain after singing for an extended time, and limited use of their high range. VHI/MVQ scores indicated that the study participants with 21 to 39 years of teaching experience had more vocal difficulties than other participants and indicated limited use of the low range of their speaking voices, inconsistency in the sound of their voices, dry throats, throat pain after singing for a prolonged time, difficulty singing softly, and the need for vocal rest. Participants with 6 or more years of experience experienced hoarseness after speaking for an extended time.
