| Abstract: | The essential prerequisite for noise control is to locate the noise sources with exactness.Different methods for identifying the noise sources are illustrated in this paper.After briefly introducing the traditional analysis methods as well as the common methods based on signal processing,the paper makes a review of the principle,speciality and utility of some new techniques developed in recent years,such as sound intensity measurement,acoustic holography and beamforming.Also summarized are the research achi... |
