摘要
本文在一封闭的房间内通过实验研究主动噪声控制技术的特性。采用一个多阶谐频信号在实验房间产生模拟的原始声场 ,并应用一多通道自适应控制系统进行降噪实验 。
In the paper, experiments on active control of noise are investigated in an enclosed room. The primary noise field is produced by a multiple frequency signal, and a multi-channel adaptive system is applied to cancel it. A lot of experiments are fulfilled and the satisfied results are obtained.
