A wind-induced noise influenced the acoustic measurements in the outdoor environment especially in the measurement of low frequency acoustic signals. In this paper, a new trial of dynamical countermeasure method for the wind-induced noise will be proposed from statistical viewpoints. For considering the effective usage of the successive information of wind velocities, by expanding the multivariate moment generating functions in the statistically orthogonalized series form, the generalized multi-variate regression model of the wind-induced noise on the wind velocisies and the dynamical computer-aided algorithm for estimating the unknown acoustic signals will be newly derived. Finally, the effectiveness of proposed method will be experimentally confirmed.
