Suppose you make noises as a function of the jerk applied to an object?  
That is, the change of the total acceleration of an object from one step
to the next?  A huge jerk might be a pretty good indicator of a collision.  

It simplifies things a bit in that your noise-making code would only be
looking at a single objects when it decides what noise to make... that
might be too simple, but then again it might be efficient and
realistic.  I dunno... comments?
