| Abstract(in English) | In this paper, a sound field monitoring technique is proposed. The proposed technique uses the time difference of short term estimated impulse response those are obtained using the cross spectrum technique with different length rectangular time window. The noise factor estimation technique from an estimated impulse response is necessary to realize such a sound field monitoring system. Authors have already proposed the noise factor estimation technique that uses a shorter rectangular time window for driving signal and longer time window for measured signal. The exact difference would be obtained with the exact estimated impulse response that are picked up using the estimated noise factor level. The proposed technique is confirmed by a measurement in an air flow condition where the air flow is driven with an air conditioner. The noise factor estimation is necessary to obtain exact impulse responses. |
