Affective Reactions to and Preference for Combinations of Interior Aircraft Sound and Vibration

Abstract

Affective reactions to the interior aircraft environment are a basic constituent of perceived ride quality. This study addresses affective reactions to combinations of interior aircraft sound and vibration. In agreement with findings from environmental psychology, it was found that the combinations of six interior aircraft sounds and vibrations (no vibration, 16 Hz, and 95 Hz) gave rise to affective reactions described by two dimension s: valence (unpleasantness-pleasantness) and activation (activated-deactivated). Moreover, preferences for the affective reactions induced by the sound-vibration combinations were related to both of the affect dimensions. Taken together, these findings suggests that (a) different combinations of sound and vibration induce different affective state and (b) by measuring preference in addition to affective reactions, ride quality optimization may be facilitated.
