无次级路径建模的反馈有源窄带噪声控制算法
A feedback active narrowband noise control algorithm with no secondary path modeling
摘要
Abstract
Aims:To circumvent secondary path modeling by offline or online methods,and reduce the computational complexity.Methods:A feedback active narrowband noise control algorithm with no secondary path modeling is proposed.The impulse response of secondary path can be expressed as a combination of the acoustic delay components and the electrical delay components of the path.Once the associated time delays are estimated,the information of the secondary path impulse response can be attained and simplified the modeling method.Results:The secondary path modeling is avoided and the feedback active narrow band noise control is realized by using the proposed algorithm,which reduces the computational complexity.If the adaptive filter length is set to 256,the computational complexity is 530.Conclusions:The single frequency,narrow band white noise and narrow band pink noise are used as the primary noise in the simulation,respectively,and results show the proposed algorithm can obtain similar noise reduction performance as the SAIMC algorithm,and has low computational complexity different length of adaptive filter.关键词
