Abstract
This paper describes an identification probrem of the source position of noise. In this research, in order to identify the source of noise, the boundary element method and the extended Kalman filter are used. First, the sound pressure of an observing point is measured. Next, when the position of a sound source is located in an assumed position, the sound pressures of observing point are calculated by the boundary element method, and the position of the sound source which is an unknown parameter is estimated with an extended Kalman filter. The validity of this technique is checked from the result of a simulation.
