I'm glad this guy got to use his paper for his Masters, but he was mistaken. Just because an audience of musicians couldn't tell, doesn't mean there is not a difference.

The president of the company I work for is famous for observing that "two things that aren't the same are different", and I'll take your word for it that there is "a difference" in tone between pipe materials; but there are differences that matter and differences that don't matter. I suspect what the UNT paper was measuring was whether there was a difference that matters. It sounds as though the difference would matter if the audience was comprised only of organ builders .

What I'd want to know, before I'd accept the paper, was the range of sizes and shapes of pipes tested, and whether they also tested difference tones.
