PM_(2.5)地图可视化中的听觉感知应用

Auditory Perception Application in PM_(2.5) Map Visualization

针对地图可视化在视觉障碍群体中存在信息传递不畅的问题,深入剖析声音发声机理,以我国2016年1月1日到1月29日以小时为节点的PM_(2.5)数据为研究对象,充分考虑空气污染等级及不同等级对应监测站点数量,构建基音音名、泛音频率与PM_(2.5)平均值之间、音量大小与不同空间污染等级涵盖的监测站点数之间的映射模型,从而获取声音参数,借助Garage Band音乐制作软件完成PM_(2.5)数据可听化,结合PowerMap创建的PM_(2.5)可视化地图,最终设计制作了PM_(2.5)动态频谱地图。本文研究对多感知通道在地图可视化过程中的应用具有借鉴意义。

It is hard to transmit information by using map visualization method among the group of people who have dysopia. In view of this problem,we analyze the mechanism of sound production thoroughly and take the PM（2.5） data of China from January 1 to January 29 in 2016 as the research object. Considering the air pollution level and the number of monitoring sites at different level,we build mapping models between the fundamental music alphabet,the frequency of overtones and the average value of PM（2.5）,the volume of overtones and the number of monitoring sites covered by different spatial pollution levels. Then,we obtain the sound parameters,achieve PM（2.5） data sonification by using Garage Band music production software,create PM（2.5） visual dynamic monitoring map by using PowerMap. Finally,we design the PM（2.5） dynamic spectrum map. The research has reference significance for the application of multisensory channel in the process of map visualization.
