- The study, conducted between October 2021 and March 2022, assessed the vocal fatigue experienced by teaching doctors who wear masks due to the COVID-19 pandemic, with data collected from 170 professionals.
- Results showed that over 50% of these teaching professionals reported vocal fatigue, with pre- and para-clinical staff experiencing more fatigue than clinical doctors, independent of the type of mask worn.
- Those with lingering respiratory issues after COVID-19 were significantly more fatigued, indicating that vocal fatigue among teaching doctors may impact their quality of life, warranting further research on effective vocal rest practices.
