汽车车内的噪声问题是汽车诞生后就无法避免的问题。以前人们将汽车噪声问题的解决方案置于生产线上(汽车的设计和制造阶段)研究,许多汽车设计与制造专家倾力研究车内噪声问题,车内噪声指标成为评判汽车豪华程度的重要参数。因为汽车设计和制造阶段的解决方案受到工业化标准、成本及流水线工艺等方面的制约,其 Noise inside the car is the problem that can not be avoided after the car is born. In the past, people put the solution to the problem of automobile noise on the production line (automobile design and manufacture stage). Many automobile design and manufacturing experts devoted themselves to studying the problem of noise inside the car. The noise index in the car became an important parameter to judge the degree of car luxury. Because automotive design and manufacturing phase of the solution by the industrial standards, cost and pipeline technology and other aspects of constraints, its
