| Abstract: | A multi-channel self-adaptive active noise control system is designed.It has four error inputs and two offset outputs.Furthermore,the structure,design method and control principle are introduced in detail.Using this system,160 Hz single-frequency sine noise,the third order harmonic sinusoidal noise and the actual noise from a certain type of submarine are experimented respectively in an ordinary closed room and the effect of 8 dB,10 dB and 20 dB are obtained respectively.The experimental result verifies the feasibility and effectiveness of the system. |
