Test your Ears! Can you "still" hear it?

Oh right, scare people because they can't hear it due to their speakers in cheap notebooks, smartphones, whatever.
If you want a real test, go see a doc. If you need to pay for it, consider moving to another country lol
17kHz is not very high, do some research. If you are not able to hear it (through reasonable speakers/headphones, obviously), it is most likely your fault because you didn't guard your ears; can be earphones (even "low" volume is bad for your ears), being cool in public loud places not guarding your ears with your hands or protectors, etc.
It's not just based on age. Sure, your range shrinks some (also in the low frequencies) but it's not a terrible thing unless you crucified your ears.
You can't undo it because the small hair things in your ears are gone/broken; better start guarding your ears, it's worth it.

btw lol @quoting the text in the video as if it was scientific facts and the 100% ultimate real test haha

Youre right about guarding the ears, but its our genetics that'll eventually lead to a loss of hearing, obviously. Just as you'll eventually lose the ability to walk, see and so on. be it before or after you die. (my former postings could be misread though, the downgrade in hearing is almost always limited to frequencies you simply dont hear by nature, and dont need to. And the loss is actually abysmally small, and not worth pointing out. It CAN be pointed out though by forcing those unnecessary Sounds)

 

Edit @ your Edit:

Well as i said before, i know little about this whole thing, all i know is that there are people (tried it with people in real life already) that may not be able to here the last sounds anymore, and all of those who cannot are mostly above 40. But if youre better informed than me, feel free to correct whatever wrongs i may have thrown out.
