Abstract: At present,the methods such as near-field acoustic holography and far-field beamforming are widely used to obtain sound locations.However,it is still limited for methods to identify both the sound power and locations of multiple sources in the far field.The sound intensity as a vector in the sound field can be measured by a three-dimensional sound intensity probe,and multiple sampling points of the sound field can be obtained by multiple probes.Meanwhile,for single pole sound source,the sound intensity in the sound field can be calculated from the sound power and the location of the source.Based on this principle,the sound sources can be identified through solving the inverse problem of the sound intensity in the sound field.Taking two sound sources with the same frequency as the studying case,a nonlinear equation set is established by synthesis three-dimensional sound intensity vectors on three probes in the sound field.By solving the equation set with numerical method,the spatial position and sound power of each sound source are obtained.The method is verified by both the simulation and the experiments in semi-anechoic chamber.The experimental results show that the maximum error of angle recognition is 3.83 degrees,which is 8.5% of the real value,and the maximum error of distance recognition is 0.1 m,which is 10% of the real distance.The results show that the method has high accuracy on both locating the source and estimating the sound power.By comparing the experimental results to the far field acoustic holography method,the proposed method shows better discrimination on nearby sources.
