Is there some technique to surpass noises when meditating?

I'm having a lot of troubles with noises. I try to close my ears with cotton, but it does not works great. Is a little bit difficult to me try to meditate rounded by noises (here, where a live, people seems to be sensible to noise, and worst, they like to put their automotive stereo system at high decibels despite the fact that it is forbidden by law (here the State does not get to apply its own laws), its like some kind "meat show"). So, is there some technique to surpass noises when meditating?
