Hey, You Kids...Off My Lawn!!!

No, it's not the latest ranting of Grampa McSame, but a news item my local San Francisco news affiliate carried. The context was a new way to combat the problem of loitering in high crime areas. The answer is a technology that struck me: "The Mosquito." an ultrasonic device that emits a high-pitched noise that only teenagers can hear.

Marketed under the banner "Kids Be Gone," the device emits a high-frequency modulated tone that has been likened to fingernails on a blackboard or a mosquito buzzing in the ear. Because the ability to hear higher frequencies fades with age, the Mosquito affects only people younger than about age 25. Also, according to the makers and various media reports, the sound does not annoy young children or dogs, only people in the 13 to 25 age bracket.[..]

A website focused on the Mosquito — www.kidsbegone.com — says studies have shown the device is safe and does not damage teenagers' hearing. The effective range is about 50 feet, according to the website.

In a sneaky twist, the same technology is available as a cellphone ring tone, alerting teens to calls that teachers, parents and other adults can't hear. The Kids Be Gone website has a link to the high frequency ring tone. In a test at The Courant, a 22-year-old said he could clearly hear the tone, while several staffers over age 25 heard nothing.

The technology rests with little tiny hair perceptors in our ears that usually die off by the age of 25. Although the manufacturers say that no permanent damage is done from The Mosquito, I'm a little wary of such assurances. The technology has been used in the UK and is now the subject of a protest for its indiscriminate use. (YouTube)

Cool. I just found a way to keep teenage boys away from my daughter.

I can't hear any more, I'm gonna sue!

General_Rennenkampf's picture

Unfortunately, for some kids my age, it's needed. Many of them are killing their own hearing with loud radios, and don't listen to other folk who want to still be hearing 15 years for now. So, this stuff is needed for a select group. Indiscriminantly Hell, No! This is a dangerous tool, and I wouldn't be surprised if results show it does damage hearing. If that is proven, then I retract everything I've said about it even being necessary for the assholes.

No-one deserves to have others damage their hearing. I know, because I was born hard of hearing. I don't want others to have to stumble through the joys of mishearing stuff and getting into trouble because of it.

Not every teen can hear it. Not ever adult cannot hear it. Don't believe the marketing crap from that company.

I heard about this a few years ago. The funny thing is, teenagers actually took the sound (or a pitch similar to it) and used it as their ringtone on their cell phones so that they can only hear it if someone calls them.

I just read a story on this where a landlord put one out in front of his building. They interviewed a twenty something who lived there who couldn't keep his windows open or stand in front of the building because of the noise. How is that right?

Actually, to clarify, they use it more for text messaging. This way they can send text messages, say under the desk, and know they got one without the teacher hearing it.

I am 35 and I can hear up to 20 khz. That includes dog whistles, calculator LCD's, dimmer switches for lights, the power supply for my computer, and the Mosquito/Teenbuzz. It is incredibly annoying, and I always ask businesses to disable it when I hear it.

This is pretty disgusting. I can't imagine that anybody would accept a different group of people being indiscriminately targeted. Imagine if the fire alarm of a building was constantly on so you had to run through the lobby everytime you went in and out. How long do you think the adults would allow that to continue? But who cares about the innocent kids who have to deal with it as long as we get rid of the "punks".

What BS. Not only teenagers can hear it--I'm a 33 year old woman, and I was walking down a city street a few months ago and we walked past one. It literally made me scream in pain, hunch over, and start yelling in incoherent confusion while my friends who could not hear it had stopped because they thought I was having a heart attack or something.

One of the huge problems is that the people who install these things can't freaking hear it. So I suspect they've got the volume turned all the way up to an unbelievable decibel level. But because the noise right on the verge of what people can and can't hear, it doesn't act like a normal noise, that gradually builds as you get closer to it. You're walking down the street and it goes from being something you can't hear to something you're totally in the middle of. Like literally standing in front of a rock concert speaker that's off, and then suddenly having it turn on full blast, playing feedback.

I live in NYC, a street-facing apartment on a busy street that's also an ambulance route. Really, I can deal with loud noise. But I can tell you from experience this is isn't noise. It's something much worse than a fire truck blaring its sirens and honking as it passes you walking on the street. It comes out of nowhere, and it's a brain-piercing pain that just stops you in your tracks. Worse, it's incredibly confusing because you can barely hear it, so you're just in pain and can't figure out what's happening. It's sort of like someone sneaking up behind you and blowing an air siren in both your ears, but when you turn around you can't see them, so you're all confusedly like "no, there's no noise source, how can it be noise? What is happening?" but the whole time you're trying to put together a coherent thought, the air siren keeps blaring nonstop.

When it happened to me, all I could think was how much it would suck if a mom with a stroller went past there. There's no way this isn't dangerous, and I'm sure it's going to lead to tinnitis at least. They should be illegal.

Let me tell you more about sound. Sound is not just something you hear, it's a force.

Sound molecules can literally cause a shift in your genetic structure. It can cause cell damage, make you seriously ill, or even make you well.

Using it as a weapon is pretty low.

#26 L.A.Confidential,

Isn't this like a microwave oven?

No. Sound waves are a different form of energy than electromagnetic waves, like microwaves, the light we see, gamma rays, and X rays. Sound waves are slower, and are based on vibration. Sound operates on different frequencies than the EM spectrum, which is based around emission of various frequencies that can span from gamma rays and X rays, to the size of the Known Universe. Microwave ovens, depending on the quality of these devices, can actually mess them up owing to the effect of microwaves on electronics.

Jack Damage's picture

I heard about this.. I don't know if it will cause serious hearing problems down the road or not... I certainly wouldn't believe the company line on it.... and I would certainly hope someone is keeping track of who is making, marketing and promoting this device... You know, so the suits will know to go after later after little Johnny and Janie find out their hearing is shot to hell and can prove they lived near one of these and weren't crusin 24/7 as teens in a tricked out ride with an ear splitting stereo system blowing out the neighborhood...That right there is your future litigant pool... A garage musician such as myself? Probably won't make the cut.. but then I already know how I got my tinnitus...

Mostly I'm figuring that the first time some 13 to 25 year old is actually annoyed by this and can see where it's coming from???? That will be the last time that particular device annoys those particular teens.... Does the powers that be plan on taking bb/pellet guns and slingshots off the market? What about your basic 9mm glock which is almost standard accutrement for your garden variety gang-banger... I'm sure one well placed shot from one of those, and that will be the end of that toy.... Destruction of private property and vandalism??? possible repurcussions for destroying one of these devices?? Yea, sure...No doubt about it... Like that ever stopped teens from doing something adults didn't want to them to before...

And just how many times will Mr. Wilson buy one of these things only to have Dennis the Menace destroy it before he throws in the towel... For that matter, how many times will Dennis let Mr. Wilson buy one before little Denny comes over the fence to pistolwhip the shit out of old man Wilson. Yea, I suspect this toy will foment that kind of response too. Ain't like 13 and 14 year olds are still settling things with their fists like when I was that age and keeping their grevances within their own age group... But they do still overreact to goofy shit like 13 or 14 year olds always have... Besides, this feels like auditory fascism wrapped up nice and neat in a little bowtie of 'revenge of the old folks'.... Thing is, puberty is, and has always been, and always will be, the most potent enemy of all kinds of fascism... And I think that is how this is going to play out.. Oddly enough for a guy my age, I find that reasurring and funny as hell....But then I guess I've always been a headbanger...So shoot me....JD

Did they invent one that only Liberals can hear?

It really stinks being a teenager. It was a long, long time ago, but I remember.

Nowhere to go, nothing to do if you weren't into playing sports or had no spending money, no place to hang out with your friends without bothering people - and it always felt that our mere *presence* bothered people - we didn't even have to be noisy. It always seems like it's ok to treat kids like second-class citizens. Kids have no rights to assembly in this society - and that's always been true.

If the kids are being obnoxious? I like the Classical Music idea. It's harmless, and they'll hate it. But, heck, if they actually *like* it, they might shut up to listen! And if, you know, Vivaldi doesn't work - try Wagner Opera.

I bet it's mostly genetic and not age-based as the company says. I've always had sensitive high-frequency hearing. I could hear when people's TVs were on 50 ft from their house. (I could hear the whine of the Flyback Transformer. I later learned this. People thought I was just nuts.)

And at that pitch, around 20kHz, it's more of a feeling inside your brain than a sound. It should be outlawed. Use classical music instead.

Work at a high school. Kids DO use the tones for texting (the rule is no cell phones in class) and it's always fun when a younger teacher hears the tone - the usual reaction is, "You're not suppose to be able to hear that."

Why not install a gadget around the perimeter of your yard instead that would spray skunk juice into the air? Just push a button inside the house when troublemakers congregate, and anything in your yard will tear out of there lickety split. The smell would eventually dissipate into the air.

i'm 27 and heard it at 12khz as well, maybe my early years as a raver have pushed it a little lower than average but who knows, i just wish i could destroy my hearing all over again.

I'm 28 and I've damaged my hearing greatly though rock concerts and such but I STILL can hear that...

I've read about this before. What I read stated that it WILL damage hearing if the decibel level is high enough, even if people cannot hear it. That means a lot of older people will suffer hearing damage from something they cannot hear, and are therefore unaware that the damage is happening.

Are the shop owners who are using this willing to damage their own hearing to keep teens away?

It's a bad idea.

Got sources? As someone already hard of hearing, I might try to get the Hearing Loss Association of America active against this.

I did a bit of digging.
Prolonged exposure to sound louder than 85 decibels will cause damage.

according to their own website, the Mosquito Device operates at a decibel level between 85 and 100, depending on the model.

In spite of the company's claims, this level of sound IS NOT SAFE.

Thankee, I'll start trying to get the HLAA to take notice. And I'm under 21 for anyone who'll start cracking "grandpa" jokes about someone with membership in the Hearing Loss Association of America.

I'll have to look into the HLAA, General. I have Meniere's Disease, which is an inner ear disorder that will slowly destroy my hearing if I am not careful to prevent attacks. I'm always looking for good information about it.

I'm 37 and i can hear it as well. Bloody annoying.

And I have seen places using Classical music. One of the shopping malls in Yellowknife, Northwest Territories, uses it in their entrances (often used by people to stand around and smoke during the winter) cranked right up. One store in Iqaluit, Nunavut, uses it to drive off loitering kids.

And it works.

PROLONGED exposure.

85 decibels is about equal to your average household vacuum cleaner, a noisy restaurant (people talking, not loud ambient music),and other common everyday things. In fact, NIOSH rates 85 dB exposure as good for 8 hours before you run the average possibility of hearing damage. The "safe" time decreases with decibels, of course. NIOSH gives 15 minutes at 100 dB, while OSHA rates it safe for 2 hours (the difference is the disagreement between NIOSH and OSHA about what level of lifetime risk for hearing impairment is acceptable).

The brief exposure of a cell phone ring or an irritating noise to get you out of a place (as long as you don't insist on hanging around for hours, every single day) has a very, very, low chance of causing permanent hearing loss.

here in the netherlands they use classical music in train station, and it work

My tinnitus sounds almost exactly like the 14.1 frequency, constantly.

44 y/o and I heard it.

I'm a 39 years old recording engineer.

I not only can hear this but i am finding that it has shown up as an artifact in one of my recordings.

The cost to re-record was about $5000.

This reminds me a lot of that "Active Denial System" which basically blasted a soundwave so horrible it made anyone in its path instantly double over in pain.

And now these high-pitched whines are being emitted and heard by everyone from ages 0-25, with many exceptions.

Why must we accept this audial assault on children, toddlers, babies, teenagers, young adults, day in and day out? The damages wreaked are incalculable.

But it's an effective "safe" tool to blindly punish anyone suspected of wrongdoing, like the ADS. A fascist state's best friend.

Prior to the onset of my high frequency tinnitus, I was very irritated by the sound emitted by the 19khz transducers used in security systems, which merchants would often leave on during business hours. This was well into my 40's, and I recently tested and found that at 57, I could still hear this sound if it was adjusted above the masking of my tinnitus. I have always believed that my hearing sensitivity made me more susceptible to tinnitus.

The information below is from the FAQ section of the web site for the Mosquito. I presume that by db they mean dbm, and there is no distance spec'd here. It could be much higher for a victim if it's mounted where someone can stand directly in front of it.

A comparison of the noise emitted by the three Mosquito™ models with common everyday sounds is as follows:

Near total silence - 0 dB
A whisper - 15 dB
Normal conversation - 60 dB
Mosquito Mark II Standard (M-85) - 85 dB
A lawnmower - 90 dB
Mosquito Mark II Maximum Volume (M-100) - 100 dB
A car horn - 110 dB
A rock concert or a jet engine - 120 dB
Mosquito Mark II Law Enforcement (M-130) - 130 dB
A gunshot or firecracker - 140 dB

sometime back somebody talked about this. they played it and I could hear it. i was over 25 at that time. the lady said she couldn't hear it. many people were able to hear it.
