Ancient echoes as clues to the structural relationship between grotto soundscapes and auditory perception
摘要
This study investigates the acoustic and auditory perceptual characteristics of six representative grottoes in the Xiang Tang Shan (XTS) Grottoes. The results show that key acoustic parameters exhibit systematic differentiation with changes in spatial scale and form, and that objective acoustic indicators display a stable structural correspondence with subjective auditory experience, with the major acoustic characteristics falling within a moderate range of the broader acoustic distribution of religious architectural spaces. The study proposes treating soundscape as an analytical dimension centered on auditory perception, with the potential to be extended toward a typological research approach. The findings help address the lack of an auditory perceptual dimension in traditional grotto typologies dominated by material form and provide a new analytical pathway for a comprehensive understanding of “living” religious practice—an issue crucial within Buddhist systems of knowledge and practice, in which sound is regarded as one of the core constitutive elements.
