用智能传感器记录潘普洛纳节期间城市声音变化，揭示节日对声景的显著影响。
When Pamplona sounds different: the soundscape transformation of San Fermin through intelligent acoustic sensors and a sound repository
- 部署低成本声学传感器网络，持续采集节日前后城市声音数据。
- 节日时整体声压级显著上升，人声活动主导城市声景。
- 公开分享真实节庆录音库，保存独特声学遗产，适合城市规划与文化研究者。
本研究展示了一个在潘普洛纳市部署的低成本声学智能传感器网络的应用案例，用于分析圣费尔明节期间城市声景的变化。传感器在节日前、中、后分阶段安装于城市不同区域，持续采集声学数据。分析表明，节日期间城市声学环境发生显著转变：整体声压级明显升高，声景模式改变，声学景观由人类活动相关声音主导。研究凸显了分布式智能声学监测系统在刻画城市声景时间动态方面的潜力，并揭示了大规模节日活动对潘普洛纳市声学格局的深刻重塑。此外，为补充客观测量，研究团队创建并公开发布了一个精选的圣费尔明节真实声音录音集合，以保存该节日独特的声学遗产。
原文摘要 · Abstract (English)
This study presents a use-case of a network of low-cost acoustic smart sensors deployed in the city of Pamplona to analyse changes in the urban soundscape during the San Fermin Festival. The sensors were installed in different areas of the city before, during, and after the event, capturing continuous acoustic data. Our analysis reveals a significant transformation in the city's sonic environment during the festive period: overall sound pressure levels increase significantly, soundscape patterns change, and the acoustic landscape becomes dominated by sounds associated with human activity. These findings highlight the potential of distributed smart acoustic monitoring systems to characterize the temporal dynamics of urban soundscapes and underscore how the large-scale event of San Fermin drastically reshapes the overall acoustic dynamics of the city of Pamplona. Additionally, to complement the objective measurements, a curated collection of real San Fermin sound recordings has been created and made publicly available, preserving the festival's unique sonic heritage.
