Short-term noise annoyance and electrodermal response as a function of sound-pressure level, cognitive task load, and noise sensitivity

Résumé

Introduction: Two aspects of noise annoyance were addressed in the present laboratory study: (1) the disturbance produced by vehicle passby noise while engaging in a challenging non-auditory task, and (2) the evaluative response elicited by the same sounds while imagining to relax at home in the absence of a primary activity. Methods and Material: In Experiment 1, N = 29 participants were exposed to short (3-6 s) pass-by recordings presented at graded levels between 50 and 70 dB(A). Concurrent with each sound presentation, they performed a visual multiple-object tracking task, and subsequently rated the annoyance of the sounds on a VAS scale. In Experiment 2, N = 30 participants judged the sounds while imagining to relax, without such a cognitive task. Results and Discussion: Annoyance was reduced when participants were engaged in the cognitively demanding task, in Experiment 1. Furthermore, when occupied with the task, annoyance slightly, but significantly increased with task load. Across both experiments, the magnitude of simultaneously recorded skin conductance responses in the first 1-4 s after the onset of stimulation increased significantly with sound pressure level. Annoyance ratings tended to be elevated across all sound levels, though significantly only in Experiment 2, in participants classified as noise sensitive based on a 52-item questionnaire. Conclusions: The results suggest that noise annoyance depends on the primary activity the listener is engaged in. They demonstrate that phasic skin conductance responses may serve as an objective correlate of the degree of annoyance experienced. Finally, noise sensitivity is once more shown to augment annoyance ratings in an additive fashion. Key Messages: Two laboratory experiments demonstrate that annoyance due to vehicle pass-by noise depends on both the kind of primary task those exposed are performing, and their individual noise sensitivity. Furthermore, skin conductance responses to the noises were shown to provide an objective measure of the degree of annoyance, primarily reflecting exposure level. Text
