Abstract(in English) Recently, the video cammeras are widely spread, it makes more opportunity to record video tape in the field. But the wind noise strongly degrades the recorded sound quality in the field. Windshield is a traditional technique that was used to reduce the wind noise effect. But windshield technique is not effective in a strong wind situations. So, in this paper , we focus on the wind noise reduction method besed on signal processing technique. Spectral Subtraction has been known as a useful noise reduction method. Under the stationary noise environment, the spectal subtraction is effective. However, under the non-stationary noise environment, it is difficult to estimate the noise component from the observed signal , so the spectal subtraction is not so effective in this case. Hence, we propose a new method by using multiple noise models to estimte the wind noise which is non-stationary noise and substract noise component by using the spectal subtraction. We held the evaluation experiment to examine the effectivity of proposal method.
