Can you hear this?

I got worried at first because I couldn't hear 8, then I realised my laptop was on mute.

With mute off, no earphones, I could hear 17 faintly and couldn't hear 18.

I then tried with some cheap earphones and could hear 18 but not 19.

I'm curious if I could hear more with better earphones.

EDIT: Tried it with ipod earphones which are better than my other pair and can hear 19 faintly.

 

Can only hear up to 19KHz. At 20 i can barely notice there's any noise at all =/

 

Im using a normal headset.

 

hmm. headphones should have a good high-frequency response because of the speakers being so small.

It isn't unheard of for people to reach 22kHz. The standard of audio encoding was chosen with that as that as the accepted human limit. The Sampling Theorem states "If a function x(t) contains no frequencies higher than B hertz, it is completely determined by giving its ordinates at a series of points spaced 1/(2B) seconds apart." (Yes, I'm Wikipedia quoting, get over it). The accepted human limit is 22kHz so 22000 is our B, and you use a filter to wipe out any higher frequency in the recording. Then 1/(2*22000) = 1/44000 or 44kHz. Little bit of head room and technical crap and you end up with 44.1kHz.

tl;dr It is possible that you can hear 22kHz, but it is VERY unlikely.

 

With my volume at 100% I can hear up to 18kHz but at 50% I can only hear up to 17kHz. With my tv on 50% or all the way up.

 

Not that unlikely... I can hear up to 22kHz as well.
Thanks for the information though, can't rep you unfortunately.

 

On earbuds, hearing 22kHz.

 

I can go up to 18kHz.

 

I got up to 19 kHz before I couldn't hear a thing. My ears hurt nao.

 

with mines at max I got up to 20 or 21

 

With crappy earphones, but volume on fairly low I could very faintly hear up to 21.
I'm kinda shocked by that, I'm frequently around musicians (and occasionally play myself), plus I've been listening to music on iPods nearly daily since I was 15...

 

maybe I can't hear all that well because I play piano fairly often?

 

I'm really intrigued here. It's true that with KHV having a young demographic that many of us wouldn't be very affected by age deterioration yet, but having 17% of the people that have posted results having truly excellent hearing seems a bit odd.

My scientist mind is going wild here. How many of the results are higher or lower due to sub-optimal equipment? Are the two close enough to negate eachother? What were the dB on each person's results? There are too many variables here!


BTW, with all the people talking about ho they can hear X if they increase the volume, it is a gradual decline. I could get you to hear 40kHz given enough decibels. I'm not sure a speaker exists yet that could produce it, but it is theoretically possible. You really should only be doing this at comfortable volumes.

 

define comfortable, because I've got different comfort zones, so to speak

 

50 to 60 dB. Since I doubt you have a way to measure the dB off hand I would go with this. Could you go back and listen to music without having to change the volume?

 

I heard up to 20.

 

I don't believe any of you.

 

I can't hear anything after 20. ;_;​

 

Horrible speakers to say the truth that are in random places in the room xD I tried it again and God my ears hurt. It's a bit difficult at 22kHZ but i can still listen to it. I guess i'm like my mother, she has ridiculously good hearing.

 

Up to 19kHz.
