Abstract

Purpose: Singers are at increased risk for voice disorders due to high vocal demands and vocal hygiene education is commonly recommended to reduce phonotrauma. However, variability exists in singers’ knowledge and implementation of these strategies. This study examined singers’ self-reported vocal hygiene practices and perceived knowledge of vocal hygiene, with a focus on differences based on professional status and formal vocal training. Method: A quantitative, cross-sectional survey was administered in five languages. Of 380 responses, two records were excluded for lack of consent, and 47 were removed due to substantial missing data, yielding a final analytic sample of 331 adult singers who self-identified as amateur or professional. Descriptive statistics summarized quantitative data. Chi-square tests of independence examined associations between (a) professional status and perceived vocal hygiene knowledge and (b) formal training and perceived knowledge. Open-ended responses were analyzed thematically. Results: Hydration (82.8%), avoiding vocal strain (69.2%), and minimizing exposure to irritants (65.3%) were the most commonly reported practices. Many participants (n=116) reported at least some knowledge of vocal hygiene. Professional singers and singers with formal training reported significantly higher levels of knowledge than amateur and untrained singers. Qualitative findings supported these results and illustrated how singers engage in vocal care. Common themes included frequent use of vocal warm-ups and semi-occluded vocal tract exercises, steam/humidification strategies, wellness practices (e.g., sleep, allergy/reflux management), and body-based techniques (e.g., laryngeal massage, Alexander Technique). Conclusions: Singers commonly report engaging in vocal hygiene practices; however, variability in perceived knowledge persists, with professional status and formal training associated with higher reported knowledge. The presence of these behaviors does not necessarily reflect depth or accuracy of knowledge, suggesting a potential knowledge-to-practice gap. These findings highlight the need for more accessible, evidence-based vocal hygiene education. Speech-language pathologists are well positioned to collaborate with voice professionals to promote consistent and informed vocal health practices among singers.
