Auditory cues, such as real-world sounds or music, influence how we perceive food. The main aim of the present study was to investigate the influence of negatively and positively valenced mixtures of musical and non-musical sounds on the affective states of participants and their perception of chocolate ice cream. Consuming ice cream while listening to liked music (LM) and while listening to the combination of liked music and pleasant sound (LMPS) conditions gave rise to more positive emotions than listening to just pleasant sound (PS). Consuming ice cream during the LM condition resulted in the longest duration of perceived sweetness. On the other hand, PS and LMPS conditions resulted in cocoa dominating for longer. Bitterness and roasted were dominant under the disliked music and unpleasant sound (DMUS) and DM conditions respectively. Positive emotions correlated well with the temporal sensory perception of sweetness and cocoa when consuming chocolate ice cream under the positively valenced auditory conditions. In contrast, negative emotions were associated with bitter and roasted tastes/flavours under the negatively valenced auditory conditions. The combination of pleasant music and non-musical sound conditions evoked more positive emotions than when either was presented in isolation. Taken together, the results of this study support the view that sensory attributes correlated well with emotions evoked when consuming ice cream under different auditory conditions varying in terms of their valence.
听觉线索，如实景声音或音乐，会影响我们对食物的感知。本研究的主要目的是调查音乐和非音乐声音的正负效价混合对参与者情感状态及其对巧克力冰淇淋感知的影响。与仅聆听愉悦声音（PS）相比，在聆听喜欢的音乐（LM）以及聆听喜欢的音乐与愉悦声音的组合（LMPS）的情况下食用冰淇淋会产生更积极的情绪。在LM条件下食用冰淇淋会使感知到的甜味持续时间最长。另一方面，PS和LMPS条件下可可味持续的时间更长。在不喜欢的音乐和不愉快声音（DMUS）以及DM条件下，苦味和烘焙味分别占主导。在正效价听觉条件下食用巧克力冰淇淋时，积极情绪与甜味和可可的时间感官感知密切相关。相比之下，在负效价听觉条件下，负面情绪与苦味和烘焙味相关。愉悦的音乐和非音乐声音条件的组合比单独呈现任何一种时都能唤起更多积极情绪。综上所述，本研究结果支持以下观点：在不同效价的听觉条件下食用冰淇淋时，感官属性与唤起的情绪密切相关。
