Fahim,
Two possibilities (coming from a complete novice, please take it with a grain of salt).
1) maybe you need more subs - not enough differentiation from the background noise.
2) If that's not the case, then perhaps it needs more stretching. I've been reading "The Zone System" by Wodaski, and the curves correction as Peter describes is step 1 of an iterative process of resetting the black level, then stretching again, etc etc.
eg. In photoshop, CONTROL-L, set the black level just below the first peak. Might only be 1 or 2 from the left (of 256).
Do the curves thing (CONTROL-M) as per Peter's example (Wodaski calls this the "standard curve"). THEN.... go back to levels and see if you have moved the histogram. You probably now have room at the left of the curve again, so reset the black level, then off to the curves screen again. Repeat until it doesn't get any better. Judicious use of the undo feature recommended.
Please excuse me too, if this is basic, but I've not seen a post here describing this process in any more detail. If there is someone more versed in the process or can explain it better, I'd be keen to hear it expressed differently too.
