Abstract

Unrelated auditory cues may alter gustatory and hedonic perceptions to food, but it is unclear whether similar effects will be observed with congruent eating-environment sounds. This is the first experimental work to demonstrate how different eating-environment sounds, varying in quality, may influence pleasantness of food samples. In this study, trained participants (n = 90) were separated into two balanced groups. The first group provided temporal pleasantness measurements during consumption of three different chocolate gelati while listening to various eating-environment sounds, and a silent control condition. This procedure was followed using a second group though with the provision of pictures related to the eating-environment sounds. Both psychoacoustical and psychological measures of sound quality were associated with gelati pleasantness. Combined audiovisual cues further amplified pleasantness ratings compared to auditory cues only. The results are further explained in terms of the effects of mood and arousal on sensory perception. Findings from this study may assist in elucidating the real life implications of the effect of sounds on food pleasantness.
