摘要
在传统声强测量技术的基础上,提出了一种新型的三维声强测量方法,并设计了相应的硬件系统和软件系统,开发出一套三维声强虚拟测量分析仪。通过对单声源声场的测量,验证了该系统的有效性和对声源定位的准确性。
Sound intensity is vector, so it is meaningful to obtain 3-D sound intensity for identifying noise sources. On the basis of the traditional method of sound intensity measurement, a new 3-D sound intensity measurement method was proposed, the corresponding hardware and software were designed, and a virtual 3-D sound intensity measurement and analysis system was developed. An experiment on a speaker has been investigated to validate the validity of the system and the correctness of noise source localization.
