How many of the frequency tones in this video can you hear? Turns out I'm alive and not hearing-impaired. But that's it. I heard no other frequencies in this video. But at my age, it appears that's normal. They say the memory is the second thing to go …and I guess hearing is the first. -via Viral Viral Videos
if you can't hear the higher freqs, your headphones or speakers could be limiting, my headphones frequency response is 21-18000hz so anything higher than about 18khz can't be reproduced by my headphones
Interestingly, now that 80s music is all over the radio, I've noticed I can't turn it up without hurting my ears. It's grating to me now, so my parents' objections to it make more sense. Sorry mom.
