[ODE] Easy Newbie Question

[coberr at scottsdaleins.com]

I have just started using ODE a little bit ago - and I think it is
fantastic!

However, I have a simple question:

In my application, I want to play a sound when two objects collide.  In
this case, there are shapes bouncing on a plane.

Initially,  I have tried to play a sound everytime there is a collision.
Specifically, I play a sound if dCollide() returns any contact points at
all.  dCollide() is called from a callback registered with dSpaceCollide().

The problem is that the sound is being played much too frequently -
obviously many contact points are created within any given small timeframe.

The solution I am considering is to only play a sound if there is a
collision AND a certain amount of time has elapsed.

My question is whether this is the best approach.

Thanks in advance for any insight or advice
