The question is, does ANR do any better at attenuating the
ear-damaging frequencies than ordinary noise attenuating headsets?

Yes.

Has anyone done scientific peer-reviewed studies?

Yes. See:

http://www.lightspeedaviation.com/tutorial101.asp

for a very good, fair tutorial on the basics of ANR. I used to point
folks to this to read about ANR even when I worked at Bose on headsets
back in 1999 on the Bose X.

I don't believe that pointers to relevant studies are on the Bose
website, but I do remember seeing a few good studies (some military)
on ANR protection when I was at Bose. I'm sure a search on line or in
the library would turn them up.
