Traditional psychoacoustic measures often lack accuracy in diagnosing hyperacusis and other sound tolerance disorders, possibly due to their reliance on artificial stimuli and unidimensional scales. The aim of this study was to assess loudness across sensory and affective dimensions using natural sounds, drawing on pain research wherein intensity and unpleasantness are assessed separately. We hypothesized that similar distinctions apply to loudness perception. A total of 102 young adults with normal to mild hearing loss rated 32 sound stimuli (pleasant, unpleasant, neutral, and artificial) at 10 intensities (40 to 100 dBA) on sensory and affective scales. They also completed the Hyperacusis Questionnaire, the Noise Sensitivity Scale, and the Hospital Anxiety and Depression Scale. Mixed linear models indicated both correlations and dissociations between scales that varied according to intensity and valence. Louder stimuli were rated as more unpleasant, but only at high intensities. On the sensory scale, sounds were perceived as louder with increasing intensity; however, at low to moderate intensities, pleasant and neutral sounds were rated as louder, whereas at higher intensities, artificial and unpleasant stimuli were rated as louder. On the affective scale, the perception of unpleasantness also increased with intensity, but less steeply. At high intensities, artificial stimuli were rated similarly to unpleasant stimuli. Noise sensitivity scores predicted louder and more unpleasant ratings, whereas depression scores were associated with softer and less pleasant perceptions. This study highlights the need for multidimensional approaches in audiology and suggests that the integration of sensory and affective scales with natural stimuli may improve the diagnosis and treatment of sound tolerance disorders.
传统的心理声学测量方法在诊断听觉过敏和其他声音耐受障碍时往往缺乏准确性，这可能是由于它们依赖人工刺激和单维量表。本研究的目的是利用自然声音，从疼痛研究中借鉴强度和不愉快程度分别评估的方法，来评估跨感觉和情感维度的响度。我们假设类似的区分也适用于响度感知。共有102名听力正常至轻度听力损失的年轻人，在感觉和情感量表上，对10种强度（40至100分贝声级）的32种声音刺激（愉悦的、不愉快的、中性的和人工的）进行评分。他们还完成了听觉过敏问卷、噪声敏感度量表和医院焦虑抑郁量表。混合线性模型表明，量表之间的相关性和解离性会根据强度和效价而变化。响度更大的刺激被评为更不愉快，但仅在高强度时如此。在感觉量表上，声音强度增加时被感知为更响亮；然而，在低至中等强度时，愉悦和中性的声音被评为更响亮，而在较高强度时，人工和不愉快的刺激被评为更响亮。在情感量表上，不愉快的感知也随强度增加，但变化幅度较小。在高强度时，人工刺激与不愉快刺激的评分相似。噪声敏感得分预测了更响亮和更不愉快的评分，而抑郁得分与更柔和和更不愉快的感知相关。这项研究强调了听力学中采用多维方法的必要性，并表明将感觉和情感量表与自然刺激相结合可能会改善声音耐受障碍的诊断和治疗。
