Abstract

Poor acoustic conditions in learning spaces have a detrimental effect on the speaker's health and constitute a risk factor for voice disorders. Previous research indicates that an acoustic refurbishment of the learning space has the potential to increase well-being and decrease voice-related health problems among teachers, but the research is scarce. In this study, we aim to investigate how different acoustic conditions affect the speaker's voice use and self-perceived speaker's comfort. Voice recordings of short speech tasks and self-evaluations of the speaker's comfort were collected from fifteen participants during a three-step acoustic refurbishment of a real-life university lecture room in an experimental setting.

Poor acoustic conditions in learning spaces have a detrimental effect on the speaker's health and constitute a risk factor for voice disorders. Previous research indicates that an acoustic refurbishment of the learning space has the potential to increase well-being and decrease voice-related health problems among teachers, but the research is scarce. In this study, we aim to investigate how different acoustic conditions affect the speaker's voice use and self-perceived speaker's comfort. Voice recordings of short speech tasks and self-evaluations of the speaker's comfort were collected from fifteen participants during a three-step acoustic refurbishment of a real-life university lecture room in an experimental setting. The influence of background babble and a classroom soundfield amplification system on vocal parameters and self-perceived speaker's comfort was also investigated. Factor analysis of the speaker's comfort questionnaire revealed a two-factor solution where factor 1 represented vocal behavior and perception of room acoustics, and factor 2 represented the perception of the task in itself. Sum scores for factors 1 and 2 will be calculated and used in a mixed-effects model investigating the effect of room acoustics on self-perceived speaker's comfort.
