maybe mine is a simplistic approach, but shouldn't this be 
one of the cases in which measuring the spectrum of true
rainfall sounds and trying to emulate it with one of 
spectrum matching techniques provides a good approach?

Do they take into account the fact that near drops have 
high frequency content which far ones have high frequency
attenuation (and they sum together)? Just thinking...

Which references do you have about this issue? 

Several months ago I wrote a patch for the generation
of colored noise, maybe it can be helful here...
