摘要

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 areshown. The results proves that acoustic holography is an effective method for the identificationof the complex noise sources.
