PURPOSE: A device and a method for removing noise are provided to remove noise without installing a sensor in indoor and to reduce a burden for calculating a sound field of a central calculating device of a noise removing device. CONSTITUTION: A device for removing noise comprises an acquisition unit(110), a noise direction estimating unit, a window opening estimating unit, a gain value calculating unit, and a control sound generating unit(140). The acquisition unit receives noise from a noise source, thereby acquiring noise data corresponding to the noise. The noise direction estimating unit estimates a direction of the noise source based on a window with the noise data. The window opening estimating unit estimates an opening extent of the window. The gain value calculating unit calculates an optimal input gain value based the opening extent of the window and the direction of the noise source. The control sound generating unit generates control sounds based on the optimal input gain value.
