| Summary: | In this paper, a new design for headset with active noise cancellation capability is presented. For the proposed headset, a Variable-Step-Size Normalized Least-Mean-Square (VSS-NLMS) algorithm is adopted in the combined audio and feedback active noise cancellation system. Experimental results
show that for the same set of signals, the average noise reduction using the proposed adaptive algorithms is 38dB compared with
36dB using Normalized Least-Mean-Square algorithm and 14 dB using the Least-Mean-Square algorithm. The speed of
convergence using the proposed approach is also faster compared with the other two cases. Informal listening tests also favor the adoption of the proposed VSS-NLMS adaptive algorithm. |
