Dacron strings on FF approved bows ?

In my experience dacron has always been louder than FF. I wouldn't even consider dacron

That's what I've found.  My indoor range is little more than a concrete box, so changes in sound and pitch are very apparent.

I can see where a recurve might pick up some noise if you went to FF and don't have anything padding either the loop or the limb.  FF is harder than B50 and might net you some additional noise from the string hitting the limb.

I shoot longbows, and every single one of them is quieter with FF than with dacron.  Start reducing strands and they get even quieter.  That's not even an option with dacron.

I only shoot recurves and have owned quite a few. I've had a couple that were too loud for my tastes and i tried dacron on them and they were much louder in every case than they were with FF

I shoot all recurves and several years ago,I put a B50 string on the first FF bow that I bought,assuming it would be quieter.Later,I bought a used bow that had a FF string.It was so quiet and vibration free,I tried one on the other bow.The FF string made it quieter and it had less vibration.I haven't put the FF on a bow yet that it hasn't reduced noise and improved handling and there have been quite a few.I know all bows are different but that's been my experience with quite a few.
