Turbulence sounds

For some time now I've been feeling the lack of something when entering turbulent conditions. I think perhaps adding some rattling sounds might help to alleivate this. I used to have a program that did this (forget now what is was called) but I found it had a frame rate hit that I didn't like. I was wondering what I'd have to learn to make such a program, perhaps a .dll that detects turbulence in FS9 and then triggers the sound. I'm not adverse to learning a programming language to do it either, as I have some experience there.Any ideas on what path I might take?- daniel
