The soundscape is an important element in the aesthetics of classical Chinese gardens and plays an important role in creating the emotional perception and mental health of visitors. The changes in the soundscape of the garden can reflect the historical changes in the garden and the changes in the pattern. As a special kind of literature, the analysis of historical soundscape can be used to interpret the ancient and modern changes in gardens. Selected poems in the Qiuxia Garden chronicle were analyzed to extract word frequencies and statistical frequencies to depict and infer the historical soundscape of the Qiuxia Garden. Then, through sound walks, six important paths in the garden were selected, and the characteristics of the soundscape perception of Qiuxia Garden today were depicted through the sound walks and participatory experiences of 23 garden visitors. Through the comparison of the past and the present, the historical characteristics of the dynamic changes of the soundscape of the Qiuxia Garden are sorted out, and suggestions are made for the appreciation, and perception, conservation and management of the garden.
