With various possibilities associated with their planning and design from walkable pockets to ample public spaces for different socio-demographic cohorts, Transit-Oriented Developments (TODs) claim to improve their residents’ quality-of-life (QoL). Having been explored from various aspects, very few studies have explored their sound implications, particularly when they reflect transportation and planning impacts. This paper explores the sound policy considerations of transportation experts and local officials, what their designers have envisioned, and the sound perceptions of TOD residents. Using in-depth interviews with policy experts, designers, and residents, this study adopted a qualitative approach. Some unorthodox findings between the residents’ perceptions and designers’ visions as well as policy experts’ attitudes toward sound emerged. While policy experts regulate and designers designate various sound sources to promote urban life in TODs, in addition to receiving these sounds, residents perceive higher sound level sources i.e., traffic. This observed discrepancy adds a different lens into transportation practice and policy that requires appropriate attention among the said stakeholders.

从适合步行的口袋到适合不同社会人口群体的充足公共空间，规划和设计都涉及多种可能性，公交导向发展（TOD）声称可以改善居民的生活质量（QoL）。从各个方面进行了探索，很少有研究探索其合理含义，尤其是当它们反映了运输和规划影响时。本文探讨了交通运输专家和地方官员的合理政策考虑，他们的设计师的构想以及对TOD居民的正确看法。通过与政策专家，设计师和居民的深入访谈，本研究采用了定性方法。在居民的感知与设计者的愿景以及政策专家对声音的态度之间出现了一些非常规的发现。在政策专家进行监管和设计人员指定各种声源以促进TOD中的城市生活的同时，除了接收这些声音之外，居民还可以感知到更高声级的声源，即交通。这种观察到的差异为运输实践和政策增加了不同的视角，需要上述利益相关者给予适当关注。
