That's the one that I mean (most recent edition):

If nothing else, it should point you to the original literature that's
relevant to your question and see how these people went about their
experiments.

That's in the F/M curves as well. There have also been experiments to
identify the ranges that are relevant to language and music. Indeed
there has been *lots* of scientific work done in this area since the
1960s. Of course all these results are statistical as they relate
objective physical measures with subjective levels of stimuli, but that
doesn't mean that it's all hogwash. ;-)
