Abstract
Acoustic holography method is applied to moving noise sources detection. A noise emitted from a driven car is measured using 64 small microphones array which is set in a lattice state, parallel to the driven direction. Noise source images are calculated from the measured data taking the Doppler effect into consideration.The measurement was carried out to detect noise sources of a driven car. As a result, the obtained distribution showed clearly noises from tires and an exhaust pipe.
