Nope, sounds like an F sharp to me.

BTW unless we're all listening on the same speakers, at the same volume and with the same ambient noise then wouldn't any perceived volumes be purely subjective?

Ross, I think I'm the only one that caught (or cared to catch) the "11" reference.

Just played for my class of second graders. It actually made one little guy tear up. I, however, didn't hear a thing. I'm hooking it up to my speakers now, just to see how many classrooms will be effected. Geez, somedays it's good to be a teacher.

What are you doing on the Café while at work? Smile
So, 4 classrooms down could hear it? that's amazing.

Well, anyone over forty who does, try it on a few different speakers with different computers if you can. If you can't hear it and have a dog, bring them into the room and see how they react, my dog just stares at the screen.

I had to crank my speakers up to full volume to hear this. There seems to be two components of this tone. One is a 19KHz tone which resides at or above normal hearing threshold. This is about the same frequency put out by old televisions. I could barely hear this at full volume and it was more of a pressure than a sound. I also heard a low pitch rumbling that I think is used to modulate the high pitch to make it even more annoying. That one is easily heard by just about everyone and may not even belong there. It might just be an artifact left over from the conversion to an audio file.

Remember too, we're listening to a compressed copy of the original. It's likely the original uncompressed tone looks totally different when looked at through something like an audio spectrum analyzer. It's easy to speculate that the original use of this tone was to pump it through high efficiency speakers and a bandpass filter that were designed for this specific tone.

Think of it as the difference between listening to the 1812 Overture with a live orchestra and cannon fire, and hearing it on AM radio through a car speaker. What we're hearing on this sample may not even be close to the real thing.

I cannot hear it. A few months ago, I played it full blast at my office. The young'ns all heard it, us old farts heard nothing. I wonder if it would be good to stop kids in the street for busking...

Well If I've learnt nothing else on the Café, I now have the magic to chase the skateboarders who hang round outside our shop.

I'm 50, and I can just barely hear something when wearing headphones if I crank the volume way up. But, I might be hearing noise made by my sound card. I didn't want to cause much ear damage, so I only listened to it briefly.

Babies can hear up to about 22,000 Hz., because their head and the bones in their ears are smaller than ours. Young adults can hear from about 18,000 to 20,000 Hz. People with bigger heads and larger ear bones won't generally hear as high frequencies as those with smaller heads. But, there are other factors.

In our society, many old people can’t hear high frequencies above much lower frequency values. We have lawnmowers, vacuum cleaners, motorcycles, and various other noisy items. Scientists used to believe that only sounds about 110 dBm and louder caused damage to high frequency hearing, but studies have shown that exposure to much lower levels for prolonged periods causes damage too.

People who live in jungles away from our modern noisy world hear high frequencies well into old age.

If you want to preserve your hearing then wear earplugs when you mow the lawn, go see fireworks, or even if you go to a really loud concert!

They now say that if you can still hear the music from headphones when you take them off your head and hold them then it’s causing cumulative ear damage when you’re wearing them.
Humans make life so interesting. Do you know that in a universe so full of wonders, they have managed to create boredom. Quite astonishing.

I'm 43 and could not hear it. My dogs and cats could all hear it.

It seems like the highest F-sharp on a piano. If you point one of those Brookstone electric dog whistles at me and turn it on, it's like hammers at my eardrum. My brother loves to whistle comparaby-pitched notes which have varied humorous effects.

This is crazy! I didn't hear a thing, but I have thre teen agers in the house nd they all came running into my magic room where I have this computer, and they said "What the %$% is that?" They said they could hear it all the way at the other end of the house!

I can't hear a flippin' thing!
