摘要：

This paper presents a new method named acoustic holography method which can be used to identify noise sources. A new formula of holography reconstruction was obtained, based on the Kirchhoff integral formula. Some simulating tests were carried out by using the new formula. Comparison with other reconstruction formulas proves that the new formula is effective. Some interesting results on the identification of the complex sound sources of a vehicle show that acoustical holography method is an effective method for complex noise.
