With these things it all depends on how you define functional hearing loss. In a practical sense there is no hearing loss if your hearing is fine up to, say, 12K, and more or less stops there. For the ability to hear slight sonic differences between cables, that does make a big difference, however.
It is well documented that adult males lose their ability to hear the highest frequencies, the older they get. Females do rather better here. So yes, I think the question mark was a very legitimate one, and not at all in bad taste, unless you think reality itself is a bad joke.
