摘要
低频噪声普遍存在于日常生活中,而有源噪声控制可以有效地解决该问题。本文以管道低频噪声为研究对象,建立了单通道前馈有源噪声控制系统模型,采用了Fx-LMS自适应滤波算法,在Lab VIEW平台下实现了算法的设计和仿真。通过仿真,验证了Fx-LMS算法的可行性和有效性,为今后进一步的实验研究奠定了理论基础。
Low-frequency noise is common in everyday life,and active noise control can effectively solve this problem.In this paper,the low-frequency pipeline noise is taken as the research object,a single-channel feedforward active noise control system model is established,and the Fx-LMS adaptive filter algorithm is used to implement the algorithm design and simulation under the LabVIEW platform.Through simulation,the feasibility and effectiveness of Fx-LMS algorithm are verified,which lays a theoretical foundation for further experimental research in the future.
