401 - Identification method of plural sound sources by using measured values with error and power spectra identification
Nakagawa N., Sekiguchi Y.
Abstract
First some identification methods of plural sound sources are introduced and then the effective identification method of plural sound sources are presented by using the measured values of sound pressure which have usually the measuring error. This is the new method which takes into consideration of weight in the evaluation function in the optimization process. The vibration velocity amplitudes and locations of plural sound sources are identified. Furthermore it is presented that power spectra of sound sources can be identified by use of this identification method.
