Can YOU hear the Mosquito noise?  

Thanks for the link. I'm 35 & I can definitely hear it. Not a pleasant sound.

Yeah that sure cuts directly in to that part of your brain responsible for headaches...

oh I'm 30..

I guess I won't be loitering at that shop.

flick.

Same sound a TV makes, and my parents can hear that at mid-fifties.

I could not hear the sound consistently until I turned the volume all the way up on my computer. Even then, the sound was not bad enough to annoy me, and it didn't persist. I would hear it for a few seconds and then it would disappear. I am 17 years old.

I can DEFINITELY hear it. Almost 27 years old.

At 43 years old, I can hear the sound a little bit, at least through the headphones I'm wearing right now. It doesn't sound very loud to me, but it is annoying, like the high-pitched whine CRTs sometimes emit. I tried cranking up my volume to full, and although the sound still didn't seem very loud to me, and it certainly wasn't what I'd call painful, I'm left with the odd feeling that I've just had my ears blasted.

At this point, I'm not sure to what extent I was hearing the actual sound one is supposed to hear, or if I was just hearing some lower-frequency encoding noise. Headline News did a story about this a week or so ago. When I saw this on TV, and was sitting on the sofa listening through my B&W P6 speakers, I didn't hear a thing.

It could be that my hearing isn't good enough to hear any of this sound without the extra high-end boost headphones can provide, or without the clue of the extraneous noise. If I play music in iTunes at the same time I play the ringtone, the ringtone is pretty much lost on me -- if this was my ringtone I'd have to be in a damn quiet room to know that my phone was ringing.

But I also have my doubts that the TV demo was valid. According to the linked article, the ringtone is based on "an ultrasonic teenager repellent, an ear-splitting 17-kilohertz buzzer". Convential NTSC analog TV tops out at 15KHz for audio. I was watching via digital satellite TV, but as far as I know DirecTV is digitizing and rebroadcasting an analog feed of Headline News. Given many factors -- the studio sound equipment, analog elements in the broadcasting chain, digital compression of the audio which might drop such high frequencies -- there might not have been anything left for Headline News's viewers to hear, no matter how good their hearing.

Is it possible you tend to listen to music very loudly, and/or go to a lot of loud concerts?

In my work place, I can't get away from white noise -- lots and lots of computers and network gear all around me, most of it with less-then-quiet fans cranking away all the time. I'd guess it's likely that has cut into my high frequency hearing a bit over the years.

In some nations, the laws are more flexible, and it's legal to send jamming noise. Not the USA.

That means we're going to start to see modern schools built with grounded aluminum sheet inside the walls and ceilings of classrooms, and the return of wire-reinforced glass. That should do wonders to curtail wireless device usage.

37. Hear it fine. My ears are still ringing. I hate sounds up in that frequency range. I'm always turning off the TVs in our conference rooms at work because they're ringing bugs me.

- Jasen.

i'm 24. played it at the office, and had a bunch of people come up to me begging to turn it off.

my co-worker next to me couldn't hear a thing and i think he is 25.

he thought i was pulling a joke on him until everybody came here complaining.

26. It hurt. Almost as if keeps on going even when I stopped playing the sound.

I could not hear it through my laptop speakers.

I could hear it through headphones with the volume all the way up.

Through my desktop speakers I could hear slightly but it was definitely giving me a headache.

I'm 34. In the 90's in college I spent a lot of time in reggae and hip hop clubs with large booming bass speakers. So I'm sure my hearing isn't the same as my teens.

17. I hear it every at random intervels during the day including in my house and I don't have that ring tone. Some people say that if you hear it your spirt is not human (aliens)

so most adult age can hear this, so maybe it's a trick so teenagers think they have something over on us (oh don't tell them about the silent vibrate button) but in reality most adult non teenagers are annoyed by this. another conspiracy to annoy parents. and remember don't tell them about the "vibrate" mode. we can't hear that either

I certainly don't take the best care of my ears. I'm in marching band, and pep band. It can get pretty loud during football/basketball games. I also go to the indy 500 every year, and I have yet to wear ear plugs. It just ruins the experience. Boy, am I going to pay for all of this later. I don't listen to music particularly loud, but it probably is louder than it should be. I tried to listen to it again, but I still didn't hear very well.

i asked my mom to listen to it and she could not hear it!!!!! But i could perfectly!!! That is really cool!!!

Yeah, my history teacher played it at maximum volume on the computer speakers this morning with a grin on his face. He couldn't hear it but god could we.

THANK YOU! I (34) have been telling my wife (43) that TVs make a noise even if the sound is off. She can't hear it and I can.

And sweet Jesus...I played that file on my Powerbook with the sound up and my reaction was "Owww!! God!!! Turn it off!!!"

But I can also hear dog whistles.

Ok... blasted it at work. I can hear it, but it doesn't kill me, but some of my colleagues were screaming. One colleague couldn't hear it at all.

And it has nothing at all do do with hearing loss due to listening to loud music.

My parents sold the TV when I was born as any overly concerned parent does, and since I almost never hear that noise at home it hasn't really canceled out for me like it does for many people.

Anybody else have their parents tell them to sit at least 6 feet from the TV because otherwise it'd hurt your eyes and you'd be affected by the "radiation?"

No, but my mom still freaks out when I have my head near the microwave while it's on. Despite that there's a visible Faraday Cage in the glass.

If you take a spectrum analyzer near the microwave, you'll still find a lot of noise in the 2-3GHz range. There's a LOT of power in a Microwave, and while the shielding does a fine job at disturbing phase, much of the magnitude sneaks through since the microwave signal is so powerful.

In other words, most ISM radios (e.g. WiFi) and Cellular phones have sub-1W transmitters. A microwave is 700-1500W.

Oh Gawd that is awful! I still here that thing ringing in my ears! But I (13) generally have very good hearing. It kinda sounds like the noise my palms lcd makes , just A LOT louder. I will see if anyone else can here that later.

PS: Don't send any more of those things, they hurt like hell!

Edit: My mom (34) can hear it well from a distance, and she has really bad ears.

I'm 37 and could hear it fine in my right ear, but not my left, where I have hearing loss at upper frequencies, but tinitus to make up for what I can't hear.

I thought my kids were pulling my leg until my older husband of 20 years could hear it also. Needless to say I have a Dr. appt. to evaluate my hearing. I had it as loud as it would go and still did not hear anything and they were all screaming turn it down.
(I'm 44)

haha my techer cant hear it so we drive the kidz insane by playing this lol

hahah that is such a good idea!!! Kids are getting too clever these days. I wish I had that ringtone when I was younger.

NO My mum told me if i sat to close to the telly i'd get SQUARE EYES AND BE UGLY (i wanted to be a model at that point but hey ho forensic science it is)
