Effects of Virtual Instruction on Educators' Voices During the COVID-19 Pandemic.

Introduction: Resulting from the COVID-19 pandemic, professionals in the United States were mandated to work virtually from home to protect the health needs of the population. The shift in setting and ergonomic factors posed a threat to the vocal health of workers, and more specifically, to those whose professions inflict significant vocal load, such as educators. This study compared the symptoms of vocal tract discomfort and self-perceived voice handicap in full-time educators between face-to-face and virtual settings. Additionally, this study sought to identify relationships between specific environmental factors and levels of discomfort.

Methods: A cross-sectional research study was conducted by distributing an online survey to 223 individuals who identified as full-time educators. This survey collected data on vocal tract symptoms during both face-to-face and virtual instruction, environmental factors of virtual work setting, personal vocal health habits, and self-perceived voice handicap in each setting.

Results: In this sample population, the shift to a virtual work setting did not result in a significant increase in the number of vocal discomfort symptoms or an increase in vocal handicap. However, environmental factors such as air quality and water intake had the strongest correlation with levels of vocal tract discomfort.

Conclusion: It is beneficial to provide resources to full-time educators regarding the risk of voice disorders and the impact of environmental factors on vocal health.
