This report presents about the comparison of the performance among four different adaptive algorithms for suppressing impulsive noise. They are filtered-x least mean square (FXLMS) algorithm, least mean M-estimate (LMM) algorithm, filtered-x least mean M-estimate (FXLMM) algorithm, and a modified FXLMM algorithm. A designed noise, which is composed of impulsive noise and background noise, is us...

In turboprop aircraft, the low-frequency noise field created by propellers is major contributor to interior vibro-acoustic field, which determines a passenger’s discomfort. This paper deals with experimental assessment of an active control (ANC) system for cabin seat headrests using two loudspeakers placed on both sides head create local zone quiet around ears. To deal time-varying disturbances...
