摘　　要：分析汽车车内噪声的危害,以及我国在车内噪声控制方面存在的不足,提出车内噪声控制的必要性及紧迫性。通过系统分析车内噪声的组成、产生途径及控制方法,指出降噪非织造材料对车内噪声控制的有效性,并就国内外车用降噪非织造材料所用纤维及其生产工艺的研究现状与发展趋势进行分析。The harm of interior noise and the deficiency existing in interior noise control of China were analyzed,and the necessity and urgency of the interior noise control were proposed. Through systematically analyzing the composition,generation and control methods of the interior noise,the effectiveness of the interior noise control with nonwovens was pointed out,and the present research situation and development trend of fibers and production processes on vehicle noise reduction with nonwovens were analyzed.
