Separable active noise control system

Abstract

The invention discloses a separable active noise control system. A controller is used for noise control in a stable sound field environment. The controller is used to divide an active noise controller into two independent modules, namely a training module and a control module. The control module has a function of simulating a sound field path, and is mainly used for the simulation of the sound field path from the reference source to the control source, and is used to reduce the sound pressure in the specific area. The training module and the control module can work in a combined manner, and are mainly used for the cooperation of the sound field paths during the active noise control. The system provided by the invention can work in the fixed control working mode and the self-adaption working mode, and is advantageous in that in the fixed control working mode, the control module can work independently; the function is single, the size is small, the cost is low, the power consumption is low, the parallelism is strong, and the processing time delay can be reduced; in the self-adaption working mode, the control module and the training module can work in a cooperative manner, and the connection is convenient and fast, the operation is simple, and the use efficiency is high, and in addition, one training module is used for a plurality of control modules, and therefore the system debugging installation can be facilitated.

Description

technical field [0001] The invention relates to the field of active noise control, in particular to a detachable active noise control system. The invention separates the traditional active noise controller in the form of a control module and a training module, which has strong versatility and high use efficiency. Particularly suitable, but not limited to, active noise control applications where the sound field is relatively stable. Background technique [0002] In recent years, with the development of industrialization and urban traffic, people's requirements for noise reduction in the surrounding environment are becoming more and more urgent. Active noise is a special noise reduction method. Compared with traditional noise control, active noise control is more effective for low-frequency noise control. In addition to its small size and flexible settings, it has a wider application prospect. Therefore, it has attracted more and more attention from academia, industry and the...
