声音是一种感官刺激物，在我们的环境中无处不在。人类已经进化出一种系统，可以有效地自动将声音感官输入转换为情感。虽然不同的情绪反应的声音具有不同的频率特性的经验认识，有一个缺乏的研究，解决不同的情绪反应，这些声音和潜在的神经机制。在这项研究中，我们研究了纯音（PT）和白色噪声（WN）输入在普通响度水平的情绪反应的影响。我们发现，WN刺激比PT刺激产生更多的厌恶反应。这种差异得到了较大的晚期后验阳性（LPP）的支持。在源定位的研究中，我们发现在LPP之前顶叶的神经活动增加。这些研究结果表明，WN刺激产生厌恶的看法相比，PT刺激，在典型的响度水平。此外，不同的情绪反应以类似的方式处理视觉刺激，反映了增加LPP激活。在普通响度水平下，WN和PT刺激的各种情绪效应可以扩展我们对噪声的不利影响以及与音乐相关的有利影响的理解。
Sound is a sensory stimulant ubiquitously found throughout our environment. Humans have evolved a system that effectively and automatically converts sound sensory inputs into emotions. Although different emotional responses to sounds with different frequency characteristics are empirically recognized, there is a paucity of studies addressing different emotional responses to these sounds and the underlying neural mechanisms. In this study, we examined effects of pure tone (PT) and white noise (WN) inputs at ordinary loudness levels on emotional responses. We found that WN stimuli produced more aversive responses than PT stimuli. This difference was endorsed by larger late posterior positivity (LPP). In a source localization study, we found increased neural activity in the parietal lobe prior to LPP. These findings show that WN stimuli produce aversive perceptions compared with PT stimuli, at typical loudness levels. In addition, different emotional responses were processed in a similar manner as visual stimulations, as reflected by increased LPP activation. Various emotional effects of WN and PT stimuli, at ordinary loudness levels, could expand our understanding of adverse effects of noise as well as favorable effects associated with music.
