摘要
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.关键词
