Indoor noise source locating method based on beam forming and transfer path analysis

The invention relates to an indoor noise source locating method based on beam forming and transfer path analysis. The indoor noise source locating method comprises the steps of: 1), collecting an acoustic pressure signal at a target position under a normal working condition; 2), finding out a maximal acoustic pressure level frequency band by spectrum analysis; 3), dividing regions of possible acoustic sources in a space; 4), finding out the maximal noise source position in each acoustic source region in the space by using a time domain BF (beam forming) method; 5), judging whether all regions are identified completely or not, if so, executing a step 6), and if not, returning to the step 4), 6), measuring path information and contribution degree from each maximal noise source to the target position by using a TPA (transfer path analysis) method, and the like. Compared with prior art, the indoor noise source locating method, disclosed by the invention, has the advantages that: the acoustic source can be accurately located; the work load of the TPA can be reduced, the noise source with the maximal control position can be found out by less TPA work load and the like.
