Abstract
Normative voice range profiles of male and female professional voice users (teachers) were reported by Heylen et al.6 Lamarche et al. have included some additional variables, including the voice area above a dynamic threshold level and the dynamic range independent of fundamental frequency, as well as the singer's own perception of vocal challenges.7 Pabon et al. added a Fourier descriptor analysis and a unification approach to VRPs.8 Herbst et al. addressed the quantitative voice class assessment of amateur choir singers.9 The VRP continues to be a standard tool in voice clinics to assess vocal capability in trained and untrained speakers.10 Recent investigations on vocal dosimetry in school teachers have shown that duration of voicing is a key variable in the establishment of a damage risk criterion for overexposure to vibration from vocalization, along with fundamental frequency and vocal intensity. For equal-energy-dissipation in vibrating tissues, a 10 dB reduction in vocal intensity allows a doubling of voicing duration.11 Duration of voicing and voice intensity appear to be inversely related if voice preservation is a concern.12 This goes along with the inverse relation between maximum voluntary muscle force and maximum duration of muscle contraction.13 Many singers struggle with the combination of high, loud, and long notes in a song, or an entire performance of songs. METHODS Subjects Twelve males, 14 females, and one male-to-female transgendered subject participated in this study (27 total) as part of a classroom assignment in one of two graduate level courses, Principles of Voice Production and Voice for Performers. Seven subjects were recorded in the official voice therapy room at the Department of Communication Sciences and Disorders at the University of Iowa, while an additional 20 subjects were recorded in the research therapy room at the National Center for Voice and Speech at the University of Utah.
