拉萨历史悠久的市中心由于各种原因保留了特殊类型的历史和文化遗产，包括强烈的宗教信仰，保护政策和缓慢的全球化。除了视觉文化遗产外，声音环境也是一种需要保护的文化遗产。本文在旅游旺季对拉萨市历史文化名城中心区声环境进行实地调查和声测的基础上，对拉萨市历史文化名城中心区的声环境进行了分析。首先，介绍了拉萨的历史城市形态和文化背景。其次，从声源的角度探讨了城市历史空间与声音的关系。这些声音的声音分类和文化意义的检查和确定。第三，从声源和声音随时间和频率变化的角度评价声环境。声压级被认为是高的历史中心，这可能会影响与文化身份相关的声源。此外，显着的变化，在中心的空间和时间上的声压级和频谱的识别是反映在当地的日常生活和社会活动的特点。最后，比较拉萨的历史中心和其他一些历史中心和广场。最后，以拉萨市为例，讨论了声景观保护的原则和研究结果可能带来的影响。
The historic city centre of Lhasa has preserved special types of historic and cultural heritage for various reasons, including strong religious beliefs, preservation policy, and slow globalisation. In addition to visual cultural heritage, the sound environment represents a cultural heritage that requires preservation. This paper presents an analysis of the sound environment of Lhasa's historic city centre based on field investigations and soundwalk measurements during the tourism high season. First, Lhasa's historic urban form and cultural background are introduced. Second, the relationship between the historic urban space and the sounds is investigated according to the sound sources. The sound taxonomy and the cultural meanings of these sounds are examined and identified. Third, the sound environments are evaluated from the perspectives of sound sources and sound changes with time and frequency. The sound pressure level is found to be high in the historic centre, which might affect the sound sources associated with cultural identities. Additionally, significant variations within the centre-both spatial and temporal-that are indentified in the sound pressure levels and spectrums are reflected in the characteristics of local daily life and social activities. Finally, comparisons are made between Lhasa's historic centre and a number of other historic centres and squares. Possible implications of the results and principles of soundscape preservation are also discussed, based on the case study of Lhasa.
