<font size="4">引子：在车辆当中，无论豪华车还是经济型车，无论是新车还是旧车，都或多或少存在着车辆噪音的问题。车内噪音量大小目前已经成为评判汽车舒适程度的指数之一。一直以来，汽车噪音都是在生产线上加以解决。但随着人们对汽车品质、车辆舒适性的需求越来越高，车辆制造成本及流水线工艺要求的因素已经慢慢使得生产制造商都不能足所有用户的需要。所以相关业内士已经研究出了在后服务市场对车辆进行隔音降噪的方法。<br>
<br>
</font><font size="4">汽车隔音工程需要处理的部位：四门、底盘、尾箱、轮弧、引擎盖、叶子板、U型槽、防火墙、顶棚。<br>
<br>
<br>
</font><font size="4"><font color="royalblue">这台JEEP噪音确实大，特别是后尾箱的轰鸣声，和底盘传出的发动机噪音。有效降低噪音可以从多方面入手，如全车隔音：全面性大幅度降低噪音；局部隔音：针对性的隔音降噪达到最理想的隔音效果。<br>
<br>
做隔音之前肯定不忘闪几张 大蟹 的战车PP了，黄色战车好看。</font></font><br>

<font size="4">隔音工程材料的材质：<br>
<br>
汽车隔音降噪工程所采用的是专门为后加装设计的不同品种的隔音材料。其中，顶级橡胶顶级隔音王主要用于车体钢板的强化处理；全车粘贴顶级隔音制振王，车身形成一个整体，加强车辆的整体感，舒适性增强！<br>
<br>
<font color="#4169e1">威宝顶级隔音王：顶级橡胶纯度更高，健康环保，无论是在高低温环境下都无任何异味，对车内驾乘人员的健康是强有力的保证。车内钣金共振是很大的一个噪音源，粘贴威宝顶级隔音王提升声音阻尼能力，有效抑制共振的产生并提高施工部位的隔声量，让动能转化为热能，减少了车内钣金的振动所产生的噪音</font></font><br>

后尾箱铁皮较薄，尾箱底部和底盘一样，在高速行使时窜入很多低频噪音以及因为铁皮薄车辆震动引起的共振，而两侧则是轮弧，两侧除了轮弧之外就是后轮叶子板，这个位置也是引起共振和风噪音的重要部位，还有后轮的胎噪、路噪、后驱的车辆 传动轴噪音等等都是从后尾箱传入车内。导致后尾箱产生严重的轰鸣声。<br>
来看看JEEP 后尾箱拆开之后是个什么情况。<br>

后尾箱还有粘贴一块隔音胶和的吸音棉，</font></font><br>
