Doing this test, I hear 14k really well and after that it drops off fast, from 15k on it sounds pretty faint.
I still hear the "hiss of a tone" after the start click up to 17k. Pretty sure I would hear 16/17k in a blind test but 18k, all I hear is the start click.
Do others hear past this and if so, are you hearing this similar to me? I wonder how accurate this is. I mean, the internet lol :notworthy::rolleyes:

The drop-off from 14k onward is pretty substantial.

I'm 57 this year, I expected worse. However, I never exposed my hearing to loudness. Even playing live, I only played in bands that understood the benefit of low stage volume. Glad for that now.
I notice my hearing is effected if I take an Aspirin or if I don't eat well or get enough sleep. Or when I remix all the loud mastered crap with that zzzz from accumulative aliasing distortion.

I was able to hear up to 18, at which point, like yourself, all I heard was the start click.

The tones began to attenuate at 16k. I could hear them, but not as well as the tone before it.

If you have the right soft are, generate your own - those ones are quite noisy and horrible, and I can't decide if I'm hearing the fundamental, or the noise that is superimposed on it!

I'm thinking the same. I actually asked my kids to listen to these and we were close to my findings, except my 6 year old said it was all irritating !
Doing this online is pretty ironic. Never the less, to some degree it gave me a measurement to more understanding about LPF on the 2-bus. Through my testing between mixing and final capture (or mastering), I've read (and tested for myself) converters translate high freqs better when we engage a LPF. I mean, think about the information converters are trying to deal with when it comes to transients and phase shifting. Chris Muth describes this benefit, thus, built the BAX.. I bought one a few years back just for those Filters and I like what it does when I engage it. I think I'll roll off some more after this test!

I can't hear 16KHz at all any longer - so I have a 5 minute 16K tone on my phone and it's great fun on the tube, or in a place with noisy teenagers - it soon generates space! Mean isn't it?

Oh man, that is awesome! We have a park just below us where the teenagers are swarming with parties at night. No one can sleep. I should put a speaker on the deck and let them have it! Right on. Stay tuned.

Update. I'm in the studio using my mastering gear and got the kids to do this once more. OMG! :coffee:

They do not notice a drop in high freq until 18k. In other words. 18k sounds just as loud as 14k. To me however, after 14k it drops off. So, without doubt I am no longer able to hear high end with accuracy. I've always used them to check my work but I know without doubt they are hired for the high freq curving when I mix now.
I am so glad I just did this again.
Mastering = 20 years and under from now on. :notworthy:

PS - it's not so good if you have a dog! They don't like it! They can't locate it though. Big grassy area outside my house, turned up the volume and they slowly came towards the house - some were convinced it was coming from the sky, somebody else said a nearby car, nobody sussed the open window!

I have packrats around my lake home. I need to clear out all the dead wood there (5 acres), which I'm trying to get to but in the mean time, those stinky critters are on my death list. I have been trapping them in my shed but wondered if they would be effected by a high Freq sound like this. I know there are things you can buy but do they work.

"turned up the volume and they slowly came towards the house"
Paul, I didn't quiet follow if the dogs were attracted to it, (even though they didn't like it)?
