Influences of current mood and noise sensitivity on judgments of noise annoyance.

Noise annoyance is one of the most studied reactions to auditory events. Previous research has demonstrated that annoyance reactions may be mediated by individual characteristics such as personality, attitudes, and noise sensitivity (traits). Transient temporary states such as an individual's current mood have been studied to a lesser extent. The author studied annoyance reactions to an everyday noise in participants who either were slightly annoyed or in a neutral affective state. The results showed that current mood had an overall effect on judgments of annoyance and on a participant's preference for sound. In addition, a participant's current mood interacted with noise sensitivity. These results indicate that both individual noise sensitivity (traits) and transient moods (states) are important for human auditory perception and evaluation.
