I ran into a post by a guy (sound engineer) who found out that he could not hear below 1150Hz, but had perfect hearing up to almost 27KHz!
Bet he had different taste in speakers.
I've never heard of that before. You realize that if what that guy said was true, he could not hear the fundamental tone of any normal guitar. Not even the very highest note. Ok, on some 24 fret electric guitar, he could probably hear the fundamental tone of the top few frets. (I think the 22nd fret is about 1173 hz, using perfect intervals starting from "A").
I just got back from string quartet rehearsal. Someone jokingly asked if we wanted to tune to A=442 like the LA Phil. I rolled my eyes. We listened to a Haydn mvmt on his Ascends, to get an interpretative idea on something specific, and they were playing about a half tone lower (must have been some period tuning I'm guessing).
Anyways, if that guy can't hear below 1150hz, he doesn't have any business working as a sound engineer. Or maybe he does, and perhaps there is something I'm missing here . . . maybe he specializes in spaceship laser effects, because, well . . .
