某些声音，例如黑板上的粉笔尖叫声，通常被认为是非常不舒服的。这项研究解决了这样的声音的听觉表征的哪些方面与对不愉快的判断有关的问题。参与者对大量声音的不悦感进行了评分，其中包括“格格”和其他令人不快的声音。然后建立了一个多变量偏最小二乘(PLS)模型，将不愉快的评级与来自听觉通路处理模型的听觉表示联系起来。通过从听觉表征预测新声音的不愉快程度，验证了偏最小二乘模型，确定了不愉快在频率-时间调制的听觉空间中的“存在区域”。观察到存在的区域对应于2500-5500赫兹的频谱频率和1-16赫兹的时间调制。(C)2008年美国声学学会。[DOI：10.1121/1.3006380]
Certain sounds, for example, the squeal of chalk on a blackboard, are typically perceived as highly unpleasant. This study addressed the question of what aspects of the auditory representation of such sounds are associated with judgments of unpleasantness. Participants rated the perceived unpleasantness of a large number of sounds that included "griding" and other unpleasant sounds. A multivariate partial least-squares (PLS) model was then built to relate the ratings of unpleasantness with an auditory representation derived from a model of processing in the auditory pathway. The "existence region" of unpleasantness in the auditory space of frequency-temporal modulation was determined after the PLS model had been validated by predicting the unpleasantness of novel sounds from the auditory representation. It was observed that the existence region corresponded to spectral frequencies between 2500 and 5500 Hz, and temporal modulations in the range 1-16 Hz. (C) 2008 Acoustical Society of America.
