摘要（英）：

The invention provides an active noise reduction control system and a method based on said system. The system includes a primary sensor, a controller, a secondary loudspeaker, an error sensor, and primary loudspeaker. The primary sensor is used for receiving noise. The primary loudspeaker is used for generating secondary noise generated from interference of the primary noise. The error sensor is used for detecting residual noise after interference as residual noise signals. The controller is used for collecting the residual noise signals and controlling the secondary noise sent by the secondary loudspeaker correspondingly. The primary loudspeaker is used for simulating noise signals. The controller is provided with a storage unit used for storing related information of noise. The primary sensor, the error sensor and the primary loudspeaker are connected with three input terminals of the controller respectively. The output terminal of the controller is connected with the secondary loudspeaker. The invention has advantages that system configuration requirements are reduced; the system get rids of control from noise lasting time; and a responding secondary sound source can be obtainedaccurately.
