简要总结
The proposed research will investigate the most effective strategy to reduce vocal exertion reported by speakers in noisy environments. Repeated vocal exertion can lead to voice problems and therefore identifying effective strategies can lead to better prevention of acquired voice disorders. This study will compare the effects of vocal rest and controlled phonation both before and after vocal exertion. The investigators hypothesize that vocal rest and controlled phonation will mitigate the negative effects of vocal exertion.
