Summary:We have been faced with the low-frequency noise problem as one of the environmental problems. It is important to locate a sound source precisely and effectively to decrease the low-frequency noise. Since the field measurement of the low-frequency noise is not easy because of the wind and various disturbances, the new measurement technique to obtain data with high accuracy is necessary. The purpose of this study is to develop a detection system of the low-frequency noise source using hyper-vision technology. It is confirmed that applicability of hyper-vision technology is promising to detect the low-frequency noise source.
