Some, but not all, bird sounds are associated with perceptions of restoration from stress and cognitive fatigue. The perceptual properties that might underpin these differences are understudied. In this online study, ratings of perceived restorative potential (PRP) and aesthetic properties of 50 bird sounds were provided by 174 residents of the United Kingdom. These were merged with data on objectively measured acoustic properties of the sounds. Regression analyses demonstrated that sound level, harmonics, and frequency, and perceptions of complexity, familiarity, and pattern, were significant predictors of PRP and cognitive and affective appraisals of bird sounds. These findings shed light on the structural and perceptual properties that may influence restorative potential of acoustic natural stimuli. Finally, through their potential associations with meaning, these findings highlight the importance of further study of semantic or meaning-based properties within the restorative environments literature.

通过声学和美学预测鸟类声音的感知恢复潜力

一些（但不是全部）鸟鸣声与从压力和认知疲劳中恢复过来的感觉有关。可能支持这些差异的感知特性尚未得到充分研究。在这项在线研究中，174 名英国居民提供了 50 种鸟鸣声的感知恢复潜力 (PRP) 和美学特性的评级。这些与客观测量的声音声学特性数据合并。回归分析表明，声级、谐波和频率以及对复杂性、熟悉度和模式的感知是 PRP 以及对鸟类声音的认知和情感评估的重要预测因素。这些发现揭示了可能影响声学自然刺激恢复潜力的结构和感知特性。最后，
