Argh! My ears!
I just discovered that my hearing is far worse than I imagined, especially in the high frequency range. My left ear can’t hear much beyond 15KHz. My right ear gives up at around 14KHz! A healthy young ears are supposed to be capable of hearing up to 20KHz. Man, I’ve lost quite a bit already. I think I’m destined to lose all my teeth and my hearing.
Of course, it’s not an official test. I just tested it using heartest.exe that someone made quickly.
Or maybe it’s just a temporary thing from my music…
