摘要

This work describes the factors limiting the performance in practical implementations of digital active noise cancellation (ANC) in commercial systems. This includes the codec delay, the secondary path variability, and the acoustic limitations. The causes for each limiting factor are studied and solutions are proposed that significantly improve system performance and robustness.
