APPARATUS FOR REDUCING FLOOR IMPACT NOISE USING ACTIVE NOISE CONTROL AND METHOD FOR THE SAME

摘要

According to an embodiment of the present invention, an apparatus for reducing floor impact noise using active noise control comprises: a signal obtaining unit which obtains a reference signal enabling to identify a noise source which generates floor impact noise caused by an impact force and an error signal needed for a location where minimizes the floor impact noise; and a controlled sound source unit which outputs a controlled sound to reduce the floor impact noise using the reference signal and the error signal.
