与沉默和各种分散注意力的技术相比，听受试者喜欢的音乐（由受试者选择）已被证明能有效减轻疼痛的影响。在利用实验诱导疼痛的研究中，参与者选择的音乐的流派、克里思和结构的范围很广，这导致了这样一种断言，即结构并不起重要作用，而是听偏好的音乐使音乐在其对疼痛感知的影响方面“功能等同”。本研究解决了这一假设，并进行了详细的分析，从三个疼痛研究中选择的音乐。音乐分析显示，音乐的音色和音调方面与疼痛耐受力和感知疼痛强度的测量之间存在显着相关性。使用分层高斯混合模型进行情绪分类，这表明大多数选择的音乐表示满意。结果表明，除了个人偏好，与音乐和听力环境的关联，音乐所表达的情感，如其声学内容所定义的，对增强与音乐的情感参与非常重要，因此提高了疼痛减轻和耐受的水平。(C)2011年美国声学学会。[DOI 10.1121/1.3621029]
Listening to preferred music (that which is chosen by the participant) has been shown to be effective in mitigating the effects of pain when compared to silence and a variety of distraction techniques. The wide range of genre, tempo, and structure in music chosen by participants in studies utilizing experimentally induced pain has led to the assertion that structure does not play a significant role, rather listening to preferred music renders the music "functionally equivalent" as regards its effect upon pain perception. This study addresses this assumption and performs detailed analysis of a selection of music chosen from three pain studies. Music analysis showed significant correlation between timbral and tonal aspects of music and measurements of pain tolerance and perceived pain intensity. Mood classification was performed using a hierarchical Gaussian Mixture Model, which indicated the majority of the chosen music expressed contentment. The results suggest that in addition to personal preference, associations with music and the listening context, emotion expressed by music, as defined by its acoustical content, is important to enhancing emotional engagement with music and therefore enhances the level of pain reduction and tolerance.
