Weird, I can hear the 17,400Hz easily (and it’s a pure tone, not a hiss), but not the 18k or 14400 one. I wonder if the 14400 one is the same pitch as my tinnitus.
I heard it and completely freaked my cat and dog out. I’m 49
- I heard it, once I turned up my volume. I have an air conditioner going and also some sort of bird convention happening outside.
The only one I couldn’t hear was the 14400. All the others were loud and clear.
It’s strange. At first I thought I couldn’t hear the 14,400, but turned the volume up and heard a very high pitched tone. Then the 17k and 18k I could hear fine, but the tones sounded lower pitched than the 14.4k. Weird harmonics at play between the tones and my tinnitus?
I heard a tone when I played the link in the OP.
I had to play them through the HTPC connected to the stereo, never heard a thing with the tablet speakers.
I"m confused. What I hear is a normal tone, a tone I can sing. Nothing high, nothing hissing. I’ve heard those “sounds only teenagers and younger can here” and I remember them being more like the ultra-high-pitched buzz of an old CRT TV set. Am I listening to the right sound? I didn’t vote, because I must be doing something wrong. What I’m hearing is around 800Hz.
Listening to these test tones, I can get to 15K Hz before I don’t hear anything.
The poll doesn’t haven’t anything for deaf or hard of hearing to vote on.
If this a high pitch sound I never heard it in my life. I didn’t listen b/c I have an earache right now.
54 here, heard all four off of AK’s 2nd link.
I’m 67, with a new pair of hearing aids. Like pulykamell, the first tone I couldn’t hear was 15KHz.
I wonder if the anti-teenager tone is the same one that phony device makes, that they claim repels mice and cockroaches?
One of my neighbors has a car with this feature. I think it’s a Chevy Malibu. When you approach the car at about 15 feet it makes a buzz and then when you are right next to the car it makes a continuous noise. As you walk away from the car at about 15 feet it makes another Buzz. I can’t tell you how much I hate that car and I don’t even know the neighbor, but I hate him, too.
Can you imagine if every car you walked by did that? You would go insane.
Edit- I tried to activate the alarm at night time by clicking the door handles and jumping on the hood, but it never made any reaction other than to make the annoying noise sound. It’s possible that it was just to keep dogs from pissing on the tires.
I’m 69 and hear it plainly. Annoying electronic whine.
I even tried it with headphones and couldn’t hear a thing, which is how I voted. Until I realized I had the volume turned all the way down on my headphone amp :p.
Yes, I can hear it at 48. Annoying, but not unbearably so at least for short periods. I live with annoying electrical whines at my job all the time, so I’d probably tolerate if I had to.
Yeah, in AK’s second link, I hear all four of them clearly. I’m 41 and I do have tinnitus or some kind of constant background high pitched ring to my hearing that I don’t notice unless it’s perfectly quiet.
I’m still trying to figure out the first link (the one in the OP), because all I hear is a normal 800HZ-ish sound, not a high-pitch whine like the others.
Now, I’m starting to wonder if my audio equipment or how my computer is playing back these audio files is somehow making this easier to hear than it should, because the 18K sound in the Buzzfeed article is clear as day to me, but the 15K sound in the Youtube link I posted isn’t.
34 and I heard it, it was awful. Felt like someone was using a knife on my eardrum.
55 and I can hear it, barely. I can hear the frequency, but have to have the volume up. It’s not a hiss - I hear the tone. Remeniscent of the 17,500 flyback frequency in CRT TV, which I could hear in another room. But it is getting more difficult the older I get.
I used to be able to hear unusually high sounds for my age, but my ability to hear very high sounds seems to have gone away. I’m a musician, so I do try to protect my hearing (though perhaps playing with other musicians has made me lose a bit of my hearing, or at least for higher sounds.)
I’m 32 and didn’t hear the sound. I used to be able to hear it, so I know what it should sound like.
When I was in my 30s, I had freaky good hearing. I went to Gallaudet as a visiting student to improve my sign language skills, and to understand Deaf culture. Every student at Gallaudet had to have an audiogram on record, even the visiting students who are hearing. An audiogram records the sounds you can hear at the Hz you can hear them. Most young adults with normal hearing hear speech sounds in the 5dB range. Hearing loss requiring intervention isn’t generally considered to begin until the 40dB range.
Audiograms actually have a negative line up to about -5dB, because some small children with normal hearing hear in that range. I could hear in that range at 20. The people who did my audiogram at Gallaudet were calling other people in to look at it, because no one had ever seen it before.
I doubt I hear that well now, but I there there is a, pardon the expression, feedback loop, when you have exceptionally good hearing. If your hear really well, loud sounds bother you more, so you protect your ears more, so you don’t lose hearing to having your ears unprotected. I was never a fan of rock concerts, but when I went, because sometimes you give in to peer pressure, I wore earplugs. People teased me mercilessly for it, but I’ll bet they can’t hear the annoying teenage buzz.
Over 50. Nothing but I have an old computer and cheap TA speakers. Normal internet radio has to be near max volume.
And now I have a migraine. Yes, I can hear it - but its immediately headache inducing.
Yeah, there is something wonky. I just tried it on my laptop, and I hear a high-pitched whine along with some white noise underneath. On my desktop, I hear a clearly audible 800hz-ish tone, something similar to the long tone you here before an emergency broadcast test. No idea why.
