You'll need something which measures the amplitude and frequency of the sound waves to 'see' a difference in the noises.  You can probably calculate a trigonometric function based on one particular wave within the measurement, but it won't hold true as the sounds fluctuate at random.  Possibly, you could even program a computer to calculate a random value between set parameters to account for this fluctuation.\nI'm not a math person.  Can't help you much more than that.

Try Audacity! It's freeware and it does the job pretty well.

like already said, you can use Realplayer or other free software alternatives.  Media Player Classic, Real Alternative, Jet Audio Basic, VLC Media Player could probably do it too

Try Sony's SoundForge.  A lot of home 'Do It Yourself' types use it.

I've used and have been very happy with a free software called Audacity. Search for it on download.com.

My first reaction is to suggest some noise cancelation earphones, but you say you do not want a device specific answer.  That walks us back from active to passive and we are talking insulation technigues to absorb sound and structural methods to scatter and reflect sound.  A masonry wall between your house and the tracks may well prove to be the most cost effective approach.  Try lookng over the Wikepedia articles referenced below.  Noise suppression and control is not a simple thing.
