为提高生活品质，减少室内噪声污染，以主动降噪技术的原理为出发点，针对柜式空调室内机运行时的噪声特点，提出了一种基于LMS自适应算法的前馈式主动降噪技术方案。根据提出的系统模型，从理论上分析了主动降噪技术系统的时滞与空间安置问题，为今后将主动降噪技术应用于家居声环境治理提供参考。%In order to improve people’ s life quality and reduce indoor noise pollution, based on the principle of active noise control ( ANC) , according to the characteristics of air conditioner noise during operation, a feedfor-ward ANC scheme based on LMS adaptive algorithm is proposed. According to the proposed system model, the time delay and spatial arrangement of the ANC system are analyzed theoretically, which provides a valuable reference for the application of ANC technology in home sound environmental management in the future.
