摘　　要：大量的试验分析表明，车厢内噪声主要峰值集中于中低频段（＜１０００ Ｈｚ），其主要来源于汽车各部分的振动。采用实时自适应有源噪声控制系统（ＡＡＮＣ）可有效地控制车内噪声。详细介绍了ＡＡＮＣ系统的设计步骤，并在某型号小客车上设计了试验系统。最后进行了路面试验，得出不同工况下的试验结果并进行了分析。A great amount of experimental analysis show that the main peaks of interior noise which are around middle and low frequency come from the vibration of every parts of the vehicles. The interior noise can get effective control by using the real time active and adaptive noise control system (AANC). This paper gives detail description of the design steps of the system and designed an experimental system for a mini bus. The road tests were made. The test results obtained from different operation states were analyzed.
