APPARATUS AND METHOD FOR NOISE CONTROL

摘要

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.
