    Author: Manternach JN, Schloneger MJ.
    Journal: J Voice; 2021 Mar; 35(2):328.e1-328.e10. PubMed ID: 31740101.
    Abstract:
    BACKGROUND: Researchers have studied various populations with high vocal doses and prevalence of related voice disorders. Teachers, singers, and university students are three such populations that have been examined extensively. No studies to date, however, have examined the voice use of music therapists and compared their voice use to these other populations. OBJECTIVE: The purpose of this investigation was to examine voice dosimeter data including phonation duration and percentage, amplitude, frequencies, and distance dose acquired over contiguous 7 day (1 week) periods by preservice music therapists, preservice music teachers, and other university students in concert with daily voice use surveys. STUDY DESIGN: This is a quantitative descriptive design. METHODS: Eight female students of varied majors (music therapy, music education, vocal performance, elementary education, and "other") in their third year of university study wore a voice dosimeter during all waking hours for 7 days. The dosimeter recorded voicing time, percentage, frequency, and estimated amplitude. Participants also completed surveys related to several parameters of vocal health, the number of hours they slept, and their voice care. RESULTS: Participants experienced relatively low vocal doses during the week. Music majors experienced more voice use than nonmusic majors. Some of the highest doses occurred during teaching demonstrations and leading of music therapy practicum sessions. CONCLUSION: Preservice music therapists and preservice music teachers may experience extreme increases in vocal load when they enter the field. Absent training protocols, these increases could be detrimental to their vocal health and long-term viability as practitioners.
