患有恐音症的人，一种涉及极端声音敏感的疾病，报告说对选择的但通常是常见的声音有明显的愤怒，厌恶和焦虑。虽然在某些人群（如大学生）中的流行率估计接近20%，但目前尚不清楚有多少百分比的人对这种“触发”声音产生了错音反应。此外，人们对所涉及的基本过程知之甚少。在这项研究中，我们的目的是描述在一般人群中的错音症状的分布，以及澄清是否引起厌恶的情绪反应，以触发声音部分是由声音本身的声学显着性，或通过识别的声音。使用多说话者的胡言乱语作为掩蔽噪声来降低参与者识别声音的能力，我们评估了参与在线研究的300名成年人中常见触发声音的识别与主观情绪反应的关系。参与者被要求倾听并识别不同水平的掩蔽噪声中嵌入的中性，不愉快和触发声音（信噪比：-30，-20，-10，0，+10 dB），然后评估他们对声音的主观判断（愉快）和对它们的情绪反应（焦虑，愤怒和厌恶）。使用参与者在量化恐音敏感性的量表上的得分，我们从分布中选择顶部和底部20%的得分者，以形成最恐音亚组（N = 66）和最少恐音亚组（N = 68）。两组人都比不愉快的声音更善于识别触发器，而不愉快的声音本身比中性声音更容易识别。两组人都能识别出令人不快的声音和触发声音的厌恶程度，但对于最厌声的那组人来说，一旦声音变得可识别，他们对负面情绪的主观评价就会大幅增加，尤其是对于触发声音。这些结果突出了触发声音的突出性，但进一步表明，学习和高阶评价的声音在恐音症中发挥了重要作用。
Individuals with misophonia, a disorder involving extreme sound sensitivity, report significant anger, disgust, and anxiety in response to select but usually common sounds. While estimates of prevalence within certain populations such as college students have approached 20%, it is currently unknown what percentage of people experience misophonic responses to such “trigger” sounds. Furthermore, there is little understanding of the fundamental processes involved. In this study, we aimed to characterize the distribution of misophonic symptoms in a general population, as well as clarify whether the aversive emotional responses to trigger sounds are partly caused by acoustic salience of the sound itself, or by recognition of the sound. Using multi-talker babble as masking noise to decrease participants' ability to identify sounds, we assessed how identification of common trigger sounds related to subjective emotional responses in 300 adults who participated in an online study. Participants were asked to listen to and identify neutral, unpleasant and trigger sounds embedded in different levels of the masking noise (signal-to-noise ratios: −30, −20, −10, 0, +10 dB), and then to evaluate their subjective judgment of the sounds (pleasantness) and emotional reactions to them (anxiety, anger, and disgust). Using participants' scores on a scale quantifying misophonia sensitivity, we selected the top and bottom 20% scorers from the distribution to form a Most-Misophonic subgroup (N = 66) and Least-Misophonic subgroup (N = 68). Both groups were better at identifying triggers than unpleasant sounds, which themselves were identified better than neutral sounds. Both groups also recognized the aversiveness of the unpleasant and trigger sounds, yet for the Most-Misophonic group, there was a greater increase in subjective ratings of negative emotions once the sounds became identifiable, especially for trigger sounds. These results highlight the heightened salience of trigger sounds, but furthermore suggest that learning and higher-order evaluation of sounds play an important role in misophonia.
