摘　　要：介绍一种基于Beamforming声全息技术的空调类产品声源识别及定位方法,该方法能够通过传声器阵列测量的声压结果计算产品表面的声场分布,从而找出产品主要噪声贡献位置,实现声源定位,最后通过压缩机声源定位试验验证该方法的有效性,试验结果表明,该方法能够在保证声源定位精度的同时缩短声源识别时间,提升空调类产品的隔声/声泄漏检测与噪声诊断效率。Based on Beamforming acoustic holography technology,the method of identifying the sound source for air-conditioning products is proposed.The method can calculate the sound field distribution on products surface by sound pressure measured by the microphone array,and it can find out the fundamental noise contribution to identify the location of the sound source.The effectiveness of the method is verified by the compressor sound source location test.The experimental results show that this method can shorten the time of sound source identification while ensuring the accuracy of sound source location,and it can improve the efficiency of acoustic insulation&leakage and noise diagnosis of air-conditioning products.
