Music is commonly used to modify mood and has attracted attention as a potential therapeutic intervention. Despite the well-recognized effects of music on mood, changes in affective perception due to music remain majorly unknown. Here, we examined if the perception of aversive stimuli could be altered by mood-changing background music. Using subjective scoring data from 17 healthy volunteers, we assessed the effect of relaxing background music (RelaxBGM), busy background music (BusyBGM), or no background music (NoBGM) conditions on response to aversive white noise stimulation. Interestingly, affective response to the white noise was selectively alleviated, and white noise-related P3 component amplitude was reduced in BusyBGM. However, affective responses as well as P3 amplitude to reference pure tone stimuli were similar regardless of background music conditions. Interestingly, heart rate (HR) increased in BusyBGM, whereas no increase in HR was found in similar distress, NoBGM condition. These findings suggest that increase in HR, which happens during BusyBGM exposure, can be a reflecting feature of music that ameliorates the affective response to aversive stimuli, possibly through selective reduction in neurophysiological responses.
音乐通常用于调节情绪，并作为一种潜在的治疗干预手段引起了人们的关注。尽管音乐对情绪的影响已得到广泛认可，但音乐引起的情感认知变化在很大程度上仍不为人知。在这里，我们研究了改变情绪的背景音乐是否能改变对厌恶刺激的感知。利用17名健康志愿者的主观评分数据，我们评估了放松背景音乐（RelaxBGM）、嘈杂背景音乐（BusyBGM）或无背景音乐（NoBGM）条件对厌恶白噪声刺激反应的影响。有趣的是，在BusyBGM中，对白噪声的情感反应被选择性减轻，且与白噪声相关的P3成分振幅降低。然而，无论背景音乐条件如何，对参考纯音刺激的情感反应以及P3振幅都相似。有趣的是，在BusyBGM中，心率（HR）增加，而在类似的无背景音乐（NoBGM）的痛苦情境中，心率没有增加。这些发现表明，在暴露于BusyBGM期间发生的心率增加可能是音乐改善对厌恶刺激情感反应的一个反映特征，可能是通过选择性降低神经生理反应实现的。
