Those of us who remember WW2 Fighters by Janes will probably remember this nice and immersive function.
If you pulled high G's, the overall sound (e.g.engine) got sort of flat, like taking out the bass and treble. The transition was smooth and started way before blackout effects set in. Together with sounds the g-loaded airframe made it was a great effect, which I haven't seen since in any other simulation.
I did real world aerobatics and think that this is quite realistic, at least I felt it this way. Now I don't know if Accu-Feel could modify the default sound output of FSX at all and expecially in this way, but it surely would be worth a try!
Cheers,
Mark
