Conference_programme: 18.3 - Voice accommodations in room acoustics and noise
Lecture: Interrelationship between subjective and instrumental voice and noise data in vocally demanding workplaces
Author(s): Szabo Portela Annika, Södersten Maria
Summary:
Objectives: To investigate how self-rated amount of voice use and perceived disturbing noise relate to instrumental measurements of phonation ratio and environmental noise over time in work and leisure conditions. Methods: Participants were 20 patients with work-related voice disorders, and 20 vocally healthy controls matched regarding age, profession and workplace. The participants, all women with vocally demanding jobs, rated estimated speaking time and perceived disturbing noise 4 times per day during 1 week. Instrumental measures of phonation ratio (percent) and of sound pressure level (dBA) of the environmental noise were registered with a portable voice and noise meter from morning to evening during the week. \nResults: Self-rated speaking time and instrumentally measured phonation ratio, as well as self-rated disturbing noise and instrumentally measured environmental noise, had similar patterns during both workdays and work-free days. \nConclusions: Self-reports of voice use and disturbing noise are useful to collect, if this is done in a structured way.
