A Study on the Active Noise Control Algorithm for Rreducing the Computation Rime

계산속도를 증가시키기 위한 능동소음제어 알고리즘에 대한 연구

When the error path can be modeled as a pure delay, an adaptive algorithm for slowly time varying system is proposed to minimize the sound pressure level. This algorithm makes it possible to use the fittered-x LMS algorithm with on-line delay modeling of the error path. Another simple adaptive algorithm for pure tone noise is proposed which eliminates the cross term in the multiple error filtered-x LMS algorithm.
