| 1 | Research on acoustic holography method for identification of sound sources显示文摘This paper presents the method named acoustic holography which can be used to identify noise sources. A new formula of holography reconstruction is obtained, based on the Kirchhoff integral formula. Some simulating tests are carried out using the new formula. The comparison with other reconstruction formulas proves that the new formula is more effective. By using acoustic holography method, some interesting results about the noise of a vehicle are shown. The results proves that acoustic holography is an effective method for the identification of the complex noise sources. | YANG Diange ZHENG Sifa LI Yukang LIAN Xiaomin JIANG Xiaoyu(Automotive Engineering Department, Tsinghua University Beijing 100084)(State Key Laboratory of Automotive Safety and Energy Beijing 100084)Received Dec. 12, 2000 | 2002 | Chinese Journal of Acoustics2002，21，4： | 2 |
