Abstract: PURPOSE: A noise control apparatus and a noise control method are provided to enable a user to easily control noise by a window integrated with a sensor and a drive unit. CONSTITUTION: A noise control apparatus(100) comprises a measuring unit(110), a sound analyzing unit(120), an inner sound field estimator(130), and a noise control unit(140). The measuring unit is located outdoors and measures sound pressure. The sound analyzing unit calculates the direction and speed of sound based on the measured sound pressure. The inner sound field estimator predicts the indoor sound field based on the direction and speed of the calculated sound. The noise control unit controls the indoor noise based on the predicted indoor sound field.

Abstract: PURPOSE: An apparatus and a method for predicting a sound source location are provided to three-dimensionally predict a location of a sound source using a small number of microphones, thereby reducing hardware size and calculation quantity. CONSTITUTION: An obtaining unit(100) obtains the nth mutual correlation value sequences about the nth microphone pairs. A mapping function applying unit(110) assigns mutual correlation values of the nth mutual correlation value sequences to corresponding coordinates of the nth coordinate system according to a preset nth mapping function. An estimating unit(120) estimates the direction of a sound source based on the allocation result.
