Abstract Focused on the inconsistency between convergence rate and steady state error in Least Mean Square (LMS) algorithm, this paper presents an improved adaptive variable step-size LMS filtering algorithm, which is applied to suppressing specific sound in home virtual sound barrier system to obtain a relative quiet area. Audio signals with a lot of white noise have been tested in the virtual sound barrier system simulated on the MATLAB platform. The simulation results show that the improved algorithm we proposed has a faster convergence rate and good sound suppression effect than traditional algorithms. This can achieve a great effect on suppressing specific sound in virtual sound barrier system for future home applications.
