摘要: PROBLEM TO BE SOLVED: To specify a generation position of sound to be detected.SOLUTION: The method for estimating source comprises the steps of: (S1) generating pair pressure data; (S2) performing short time Fourier transformation processing calculate frequency intensities Pand P; (S3) extracting bandwidth data detected in zone which is generated and continued; (S4) calculating after-normalization (S5) differences Pin intensities; (S6) maximum cross correlation between (S7) autocorrelation difference Por (S8) multiplying by an acoustic velocity distance from sampling original each data.
