Test your hearing!

[WorldLeader]

Here is a cool site where you can test what frequencies you max out on. The average is around 15 KHz for adults. Try it!

Here is a sample for you to try right here: 16 KHz

I maxed out around 18 KHz, but I'm pretty young. Where do you max out at??


PS: Why do they sell 20hz-20khz speakers if no one can hear them?

Oh, this is a duplicate thread, sorry! Should've scrolled a bit further down the page.

I could hear the 17000 hz, but not the 18000 hz, and I'm 28. Thanks for the link.

Test assumptions

This type of test assumes that your speakers have a flat frequency response up to 20 K Hz. If you try the test with a pair of Bose cubes, for example, the speakers will cutt out well before your hearing does.

Excellent point. Most headphones or earbuds are not able to produce frequencies at the upper range of human hearing either.

I maxed out at 18000 and I'm almost 30

I could hear all of them. Is he sure that last one is 25kHz?

edit: Just loaded the 25kHz tone in Audacity and this is what it showed me:

Looks like it maxes out at 24984Hz. Is it possible that my sound card is somehow processing this so that it isn't outputting it as high as it should? I just find it hard to believe I can hear that high of a frequency.

It also assumes that the speakers don't introduce harmonic distortion lower than the signal itself.

Vart, yes it is at 25KHz(I just confirmed this with Sound Forge) so if you can hear this and it doesn't sound higher than some of the others then it has to be distortion

cheers

 

[Vart]

I'm definitely hearing something other than distortion. Maybe I can just hear high frequencies. I do know when I walk in to a room I can tell if there is anything electronic on just by listening for that high pitched noise.

 

[WorldLeader]

Wow, you can really hear the 25 KHz? That is almost unheard of!

I can also tell when a TV is on in a room, it drives me crazy

I'll have to test my wife's hearing

My brides hearing is perfect. (or so she says)
Except for the fact she can't hear my voice.
Is it possible, she's ignoring me?

 

[Octane]

I could hear 19,000 just fine and I could barely hear 20,000. I am 14 years old.

 

[Rik]

heard up to 20, not bad for ears that have been tortured for 37 years.

What equipment are you using to play the tones?

I can hear the 17KHz easily and the 18KHz almost as easily but nothing above that. I played them through the PC with a SPDIF connection directly from the motherboard to the 3805(Eq off) and through the Wharfedale Modus one-six's(apparently rated at 30Hz-25KHz) I used a digital SPL meter to check the SPL at about 6" from the tweeter and set the output at 100db(C weighted). All the way up to 17Khz the output was around 100db, 18Khz was 98db, 19KHz was 81db, and 20 KHz was indistinguishable from the daytime background noise(which hovered around 40-60db). The sharp drop off from 19KHz-20KHz could be due to the inability of the anything in the chain, but most likely the speakers(possibly also the SPL meter, I don't know what it's rated at)

cheers

And, your room is soundproofed? I didn't try it, no speakers on comp, but does the level change too?

Or, most likely IM as has been shown in some AES papers why people reported hearing beyond 20kHz in music. Speakers introduced a great amount of IM that became audible.

A very small population can hear beyond 20kHz. This also has been reported in some AES papers.

Well, if you take care of your hearing now, instead of much later when the damage is done, you will enjoy that higher range

 

[mtrycrafts]

Another consideration

Even though one might have a good upper band, they may have some hearing loss in other bands, especially in the mid band, 2kHz-4kHz, meaning that they need a higher threshold to detect.

i could hear the 17000 hz.

thanks for that site.
