定向震源

Based on the algorithm , the modeling methods of complex situations such as curved surfaces , partial absorption , directional sources , multiple sources and various sound barriers , have been presented . then , the objective modeling ( parameter prediction ) and the subjective modeling ( binaural auralization ) of enclosed sound fields have been studied in detail . in order to verify the above algorithms , the results worked out by our computer program have been compared with those of measurement in real buildings , calculating by statistical method , modeling by other researchers and a kindred software
声场视听一体化是在封闭声场参数预测( parameterprediction ) 、可听化( auralization )和可视化( visualization )基础上提出的一个新的概念，其本质含义是：在一定的声学、数学和信号处理理论基础上，通过建立三维声场的计算机模型，实现从客观声学指标、主观听觉感受和直观视觉效果三方面对三维封闭声场进行综合的预测和评价。
