 1、
汽车轮胎与地面摩擦的声音。这种声音基本上属于低音而且伴随着振动。这种情况尤其邻近的是混凝土的公路比柏油路的要严重。
 2、
汽车发动机、排气管、汽车传动系统的声音。马力越大、使用车限越长的车辆，这方面的噪音就越强。
 3、
汽车喇叭、风阻和刹车、减速带及承载物撞击引起的车辆振动的声音。
 知道了噪音的主要来源和分类，我可以就可以逐个解决。
 1、对付噪音的最好办法就是窗户要严封，不管你是单层窗还是双层窗，密封是最主要的。木桶的承载量是由最短的木片决定的，而隔音效果是由最弱的一环决定的。从现在的技术水平来说，用塑钢窗来做为密封的手段是最有效的装修方案。对于已经采用铝合金的用户，应该确保铝合金的边框的密封条的完好。相对而言，铝合金窗的密封性要比塑钢窗差。
 2、窗户密封解决了，下一步就是要使其更密封，毕竟隔音不是说密封了就行的，还得看密封性能。在塑钢窗中采用中空玻璃就是一个很有效的办法。因为最噪人的往往是高音部分，而高音是直线传播的，用玻璃可以使其大部分反射，中空玻璃则可以使其没有反射的部分消耗殒尽。但是要注意奸商把没经过处理的双层玻璃当中空玻璃卖给你。
 3、通过使用厚质窗帘来可消耗部分声音的能量，也是一种较简单的办法，当然并不是一件非常有效的办法。
 4、
对于振动摩擦这些中低音，我们可以采用地毯，织物甚至吸（隔）音棉等来减弱他们对室内的影响。在床脚加装胶垫也可以减轻一定的振动感。同时床垫采用棕榈垫也要比采用弹簧的席梦思好，当然，硬床板就更不用说了。
 5、
现在有一些房子采用轻质砖（空心砖）做外墙，这些材料密封性较差，如果你所处公路边对你影响很大的话，还可以在靠马路的墙上做一道木方（轻钢）加纸面石膏板内充吸（隔）音棉的夹层，然后再用墙纸之类的装饰表面（当然也可以采用普通的墙漆处理表面）。
 6、
当然，无论怎么做隔音，也不要忘了适当的通风，太封闭的环境对睡眠一样不健康。在面向噪音的一边要防噪，对于背对的一边也要适当地保持通风条件，当然适当地并不是要求你窗户洞开，因为噪音的东西都有一定的回响的，它可能会影响你后面的楼宇又传回来你所在的楼宇的。
 以上的做法，我们是针对马路边的噪音而处理的，其实对于其他的噪音同样有效。但一般来说，交通噪音是最主要的噪音种类，所以解决了交通噪音也就解决了其他的噪音。当然，对于打桩之类的噪音，有但不是长远的，只能通过向环保局之类的机构投诉来解决，毕竟打桩声音的强度太大，一般的隔音措施较难防范，事实上我们也没必要为了防止短期的噪音而去做试音室的隔音装修标准。
