Abstract：
Sound serves as a potent medium for emotional well-being, with phenomena like the autonomous sensory meridian response (ASMR) showing a unique capacity for inducing relaxation and alleviating stress. This study aimed to understand how tingling sensations (and, for comparison, pleasant feelings) that such videos induce relate to acoustic features, using a broader range of ASMR videos as stimuli. The sound texture statistics and their timing predictive of tingling and pleasantness were identified through L1-regularized linear regression. Tingling was well-predicted (r = 0.52), predominantly by the envelope of frequencies near 5 kHz in the 1500 to 750 ms period before the response: stronger tingling was associated with a lower amplitude around the 5 kHz frequency range. This finding was further validated using an independent set of ASMR sounds. The prediction of pleasantness was more challenging (r = 0.26), requiring a longer effective time window, threefold that for tingling. These results enhance our understanding of how specific acoustic elements can induce tingling sensations, and how these elements differ from those that induce pleasant feelings. Our findings have potential applications in optimizing ASMR stimuli to improve quality of life and alleviate stress and anxiety, thus expanding the scope of ASMR stimulus production beyond traditional methods. This article is part of the theme issue \'Sensing and feeling: an integrative approach to sensory processing and emotional experience\'.
摘要：
声音是情绪健康的有效媒介，自主感觉子午线反应（ASMR）等现象显示出诱导放松和缓解压力的独特能力。这项研究旨在了解刺痛的感觉(以及，为了比较，愉快的感觉)，这些视频引起的与声学特征有关，使用更广泛的ASMR视频作为刺激。通过L1正则化线性回归确定了声音纹理统计数据及其对刺痛和愉悦的时间预测。刺痛预测良好(r=0.52)，主要是在反应前的1500至750ms期间，在5kHz附近的频率包络：更强的刺痛与5kHz频率范围附近的较低振幅相关。使用一组独立的ASMR声音进一步验证了这一发现。快乐的预测更具挑战性(r=0.26)，需要更长的有效时间窗口，刺痛的三倍。这些结果增强了我们对特定声学元素如何引起刺痛感的理解，以及这些元素如何不同于那些引起愉快感觉的元素。我们的发现在优化ASMR刺激以改善生活质量并减轻压力和焦虑方面具有潜在的应用。从而将ASMR刺激产生的范围扩大到传统方法之外。本文是主题为“感觉和感觉：感觉处理和情感体验的综合方法”的一部分。
