I suspect the approaches used were a little too 'ex libris'. Instead of trying to model the physics, listen to the sound, think about what is happening, then take a quick peek in the book and find out claps are impulses i.e. unit pulses and therefore excite all frequencies. In other words, the room is as important as the clap. I suspect all good clap tracks include room reverb and well placed mics. I've heard it said a blind man can go into a new room, clap his hands, and instantly know where the walls, doors, and obstacles are.

I'll see about copying the relevant pages from Chamberlin and posting them on my web site. A good one for CSound simulation.
