摘要
传统的高速列车噪声控制多采用隔音、减振等被动的降噪方法,仅对中高频噪声的控制有效,无法满足时速300 km以上高速列车的噪声控制要求.而主动噪声控制技术通过有目的地产生一个次级声信号来消弭低频噪声,适于高速列车车厢内噪声控制.无论次级声源控制还是次级力源控制,都要增强系统的可靠性和鲁棒性,而宽带噪声控制的多通道自适应噪声主动控制技术将会成为该领域的研究热点.
The traditional method of high-speed train noise control use passive noise reduction methods,such as sound insulation,vibration reduction and so on,but only the high-frequency noise control effective,which can＇t meet the requirements of more than 300 km/h high-speed train noise control.In order to eliminate low-frequency noise purposely,the active noise control for high-speed trains generate the secondary acoustic signal.Whether the secondary sound source control or secondary force source of control,the noise control methods should enhance system reliability and robustness,and the broadband multi-channel adaptive active noise control technology will become the research focus.
