Patent number: 11948547Abstract: An active noise control system selects one reference sensor providing a reference signal with the largest coherence to a noise signal, among a plurality of available reference sensors, as a first entry of a reference sensor set. After selecting the first entry, the active noise control system repeats a process in which a sensor capable of providing the largest information quantity to a current reference sensor set among remaining sensors is selected as a new entry of a reference sensor set, until a desired number of sensors is reached or a desired control level is reached. When the reference sensor set is determined, the active noise control system utilizes the entries of the reference sensor set to generates a noise control signal suitable for canceling the noise signal.Type: GrantFiled: September 2, 2022Date of Patent: April 2, 2024Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATION, SEOUL NATIONAL UNIVERSITY R&DB FOUNDATIONInventors: Mun Hwan Cho, Kaang Dok Yee, Chi Sung Oh, Jung Keun You, Yun Seol Park, Yeon June Kang
