| Abstract: | A duct active noise control(ANC) experimental platform including the physical system,hardware and software system was designed to control a DC motor operating noise.The parameters for the single channel ANC algorithms were optimized to achieve the maximum noise reduction when the practical DC motor operating noise was applied.With these optimized algorithm parameters,several experiments were conducted for both single channel and multi-channel duct ANC system to control the DC motor operating noise.The exper... |
