摘要
该文论证了声强与时延相结合的含噪声源定位方法,继承了已经研究成熟的时延定位法,结合安防场所特殊的声音环境和突发事件声音特点,提出了采用声强触发定位的新思路,顺利地将声源定位的方法引入了安防领域,并针对特定的情况,提出相应的解决方法,取得了很好的效果,为以后安全防卫开创了一个新途径。
The paper is put forward to deal with the problem of exceptional sound source locality in security field.In this paper,time delay estimation algorithm and the amplitude of sound is combined to discuss.Because the amplitude of exceptional sound in security field is quite different from the ordinary.And this is also the key to touch off the action of locality.The method is simple but available.
