Delaunay三角剖分在噪声监控软件系统中的应用

Application of Delaunay Triangulation to Noise Monitoring System

噪声已经成为影响人们身心健康的四大环境公害之一。为了全天候连续时间连续空间监测噪声,引入了Delaunay三角剖分算法,将声压级映射为颜色,并绘制成图像。应用结果表明,该系统可以方便地判断某一区域的声压强弱。

Environmental noise affects physical and mental health of human being seriously.In order to monitor noise continuously,the graph of sound pressure level based on Delaunay triangulation is drawn.Results show that the magnitude of sound pressure can be estimated directly through the system.
