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.
