摘要
本文阐述了自适应噪声主动控制理论(Adaptive Active Noise Control,AANC),并详细介绍了主动降噪系统的组成和应用原理。为验证主动降噪系统的效果,在某家用三厢轿车上建立了自适应噪声主动控制系统,并在半消声室对车内噪声问题进行声学标定和调试。标定完成后,通过实车测试常用的定速和加速等工况证明采用主动降噪系统能有效降低车内噪声,尤其是低频噪声。
This paper explained the adaptive active noise control theory(Adaptive Active Noise Control,abbreviation is AANC). It also Introduce the composition and the principles of the active noise reduction system.In order to verify the effect of active noise reduction system,established an adaptive active noise control system on a family sedan vehicle.And calibrated and tuned up the system parameters for the vehicle interior noise in a semi-anechoic chamber.After acoustic calibration,the vehicle NVH test result of constant speed and acceleration conditions showed that the active noise control system can effectively reduce the vehicle interior noise,especially low frequency noise.
