and my parents cant hear it at all, but i hear it clear as day, they say you may ot be able to hear it older then 20

 

That made my ears hurt!

That is very high pitched!

 

it 17 kilohertz, i dont hink its dangerous just EXTREMELY loud(although it may not seem it)

 

i could hear it and i'm 30

 

I heard it and im 26 dang that was a high pitch!!!

 

i didn't hear it..and im young

 

I hear it just fine, I know for sure my Dad wouldn't be able to. He lost quite a bit of hearing when he was in the Navy as a diesel engine mechanic. He can't hear the clickwheel on an iPod and a lot of other faint sounds/high pitched sounds.

 

isnt human hearing limited to like 20 or 21 kilohertz

 

i caould here it fine, that is a sound i wish i couldn't hear though

 

Heard it fine... But yeah, wish I couldn't! That is annoying!
