ABSTRACT
In this study, active noise reduction device is designed based on Filtered-X least mean square (FX-LMS) algorithm, which can reduce the traffic noise in low-frequency stage. There are three main modules in this device: active noise control system, intelligent control system and noise test and evaluation system. The result shows that FX-LMS algorithm has a good denoising effect on low-frequency traffic noise in a certain frequency band.
