城市声景观参与式感知客户端软件研制

Development of Mobile Application for Urban Participatory Soundscape Sensing

城市声景观的研究为积极主动的改善声环境带来了新思路,但目前研究尺度较小,难以全面阐述城市声景观的整体质量。手机等移动设备性能不断提高,以及网络覆盖范围的扩大,增强了公众获取和分享周边环境信息的能力。借助网络和移动计算技术,发展了城市声景观参与式感知研究方法,并研制了相应的客户端应用软件。该软件能够在公众参与下对城市声景观大尺度抽样,获取参与者身边的声景观相关数据,如声要素、空间要素、主观评价要素、参与者个体特征、时间要素和其他辅助要素。该软件自2016年6月在各大主流市场稳定发布后,截至今年11月用户已经达到4 895名,返回评价记录数5 848条,月均新增用户683名,月均活跃用户1 530名,月均应用启动次数4 132次,逐渐形成了一个全球范围内的城市声景观信息收集和研究平台。

Urban soundscape research provides proactive solutions for the improvement of the acoustic environment, but current research is mainly carried out at small scales, which is difficult to generally describe urban soundscape quality. The improved performance of mobile devices, e.g. mobile phones, and enlarged network coverage enhances the public's ability to gather and share environment information. The method of participatory sensing for urban soundscape research was proposed by using network and mobile computing technologies. Meanwhile the corresponding application software was developed,which can be used to collect soundscape data including sound and spatial elements, as well as subjective evaluations, and in-formation on participants' demographics, time and accessories. The users have reached 4 895, and the returned records have reached 5 838 from June to November, 2016. The monthly new added participants are 683, the monthly actively participants are 1 530, and the monthly boot time of the software are 4 132. A platform for urban soundscape information collection and research is gradually formed around the world.
