다중채널 LMS 알고리즘을 이용한 자동차 내부 소음의 능동제어 = Active Control of Noise in a Car Using Multi-channel LMS Algorithms

다국어 초록 (Multilingual Abstract)

In this paper, Multi-channel Active Noise Control(ANC) technique is proposed to cancel the noise from the inside of vehicle using engine.
The algorithm used in the ANC system has better features for cancelling narrow and broad-band noise than conventional multi-channel ANC system. The broad-band ANC technique is especially applied in this study. The evaluation of the results through fft data processing after computer simulation about a closing space for experimentation is considered to verify the feasibility of the technique.
The results shows that the noises measured from the engine inside of a vehicle were converged to low frequency band. Multi-channel LMS algorithm is used to remove the noises of the low frequency band. The results of the computer simulation show that the low frequency noises are reduced.
