Driving Away Teens With High Frequency Noise 1035

Posted by ScuttleMonkey from the get-off-my-lawn dept.
ars writes "The New York Times is reporting on a device called the Mosquito invented by Howard Stapleton designed to drive teens away by emitting a high frequency noise at 75db. Apparently most older people can not hear the sounds, but teens can not stand it. Reports are that it works quite well, but some older people can hear it too. He found the prefect irritating sound by experimenting on his children."

      I seriously doubt it. This just takes advantage of high frequency sounds that you can hear when you're younger, but don't necessarily find yourself completely unable to stand. A perfect example of this sound was the high pitched whine of the old televisions.

        I'm 29 and NEW televisions still bother me, high def sets with higher scan rates notwithstanding. I can hear my TV set right now, and it's about ten feet away. 15 kHz is audible for me even at relatively low volume. At sufficient levels, I can hear 23 kHz. Not perceive. Not feel. Hear. It's a very annoying squeal if you have the "pleasure" of hearing it. I haven't been able to produce enough volume to hear frequencies any higher than that. Speaker roll-off kind of bites you in the backside above about 18kHz.

        Heaven help me if I'm in a room with a TV where the flyback is really whining because of a missing sync signal.... The light dimmers at work piss me off because they hurt my ears. Many of my friends (even some younger ones) can barely hear them. Defective computer monitors? Torture. I'm told the lowest sync rate on VGA is 30 kHz, so I figure there must be a frequency divider somewhere, but I'm starting to wonder if I'm a bat or something. After my last job (slight flicker and lots of whine, with near-daily migraines), I now refuse to use any non-LCD displays when working with computers.

        I'll say this: as someone who takes care of my ears, if a store I shopped at regularly put one of these things in, I can be fairly certain that it would bother me well into my 40s. And I would choose to shop elsewhere. Companies should take into serious consideration that doing this sort of thing -will- undoubtedly drive away some of their actual customers....

        For now, I'll just stay away from people with dogs. :-D

          You can actually calculate what the audible frequency is of a TV.

          For NTSC in North America:

          • 60 Hz (refresh rate) * 525 (# of lines) / 2 (interleaved, ya know!) = 15,750 Hz (15.75kHz)

          For PAL in the UK:

          • 50 Hz (refresh rate) * 625 (# of lines) / 2 (interleaved, too!) = 15,625 Hz (15.625 kHz)

          And yes, the sound drives me crazy, too. I'm 30 and an audio engineer. And I'm the only one in my household who can hear the damn TVs whining. :-)

    Yet another way for parents to avoid spending time with their kids. Seriously why the heck would anyone come up with this sort of thing? As someone who works with teenagers a lot already, I have to say I'm a bit annoyed. Tons of the kids I work with through our church have parents who I swear can't be bothered to give their kids the nurture and self respect they need. Instead they just buy them things. At least an iPod nano to an unloved kid makes the kid cool at school. This'll just drive them to try more medications designed for chemical imbalances that won't fix depression brought on by these sorts of situations.

        The sound is only annoying with constant exposure, and the only way someone is going to be constantly exposed is if they're loitering around outside the store. It will have no effect on people who are legitimate customers entering or leaving the store. No one, regardless of age, should be loitering outside this guy's store. And if there's a simply way to encourage a group not to loiter, especially when the loiterers are pretty much exclusively composed of that group, then I say "go for it!"

          You should know full well that these restrictions have nothing in common with a device designed exclusivly to annoy and frustrate a given demographic. As a 22 year old who hears high frequencies very loudly (I can hear almost all screens whistle) I can imagine the havoc this will cause not just with teenagers, but with parents that have babies (who have even higher auditory ranges), with children wating outside while their mother shops and with people walking their dogs on the footpath. There are many legitimate uses for the public land outside this store and the public has the right to use it for things like waiting and pedestrian transport regardless of their age. I've met store owners that believe that they own the public land around where they are, such as one particually charitable gentleman who demanded my spastic uncle be moved from near his shop to improve the ambience, but they are invariably wrong. Public land belongs to the public, at least where I live.

          I find the public's callous attitudes towards teenagers to be disgusting. Sure, teenagers are stupid, boring to talk to and nearly everything they do is pointless, but this also applies to people who are mentally handicapped. Yet if someone was to invent the Retard-Prod(tm) that jabs everyone with an IQ less than 60, the inventor would be lynched within a day. I was a teenager 2 years ago, I was pretty stupid back when I was 15, in the same way I'll discover I'm stupid now in another six or seven years, but generally I didn't hurt anyone and only wanted to mind my own buisiness and have other people mind theirs, most teenagers are like that. Picking on kids because you don't like their demographic is not cool and it never will be.

    Does this really work because they're teenagers, or because they just haven't lost the upper levels of their hearing? I remember reading that we can (originally) hear up to 30,000 Hz, but as we get exposed to loud noises, we gradually get more and more deaf as our ears lose more and more of their capability. Something like the first concert you go to cuts out the upper 2000 Hz of your hearing. Which brings up an interesting point - will this work on teens exposed to so much loud noises (music, lots of concerts, construction, trains, etc.) that it just won't work on them?

    By the way, a great role model for fathers everywhere:

    "Okay honey, how much does this hurt?"

      A little of both. The horizontal scanning frequency is 15,750 Hz (I think) and some but not all teens could hear it. I could, and going into a TV store would drive me nuts. Time and lots of rock and roll has cured that problem, and I no longer hear the TV sound.

      So yes sound wave could be tuned so that some, but not all could hear it. You might annoy some adults, and be ignored by other kids.

    At least, it seems like it to me.
    Back in the days of dos, pascal and c programming in a text based ide, I used to run high pitched noises out through the pc speaker. I believe I specified something between 21,000 and 24,000 hz - although I'm fairly sure that the speaker wasn't exactly tuned (although it did go a bit higher (27,000-ish hz), although only a few of us were able to hear it - we had the computer randomly play these high pitched tones and the monitor would change color about 5 seconds after the tone started, so it was sort of a double blind test)
    Yeah, high school was tons of fun.
    Anyways... Even though the old folks might not be able to hear it consciously, it still affects them. People become moody, short tempered, and in general, quite bitchy. I honestly can't say that it is due to the effects of the sound - or the effects of interacting with people who are able to consciously hear it, but - to me, at least - it doesn't really matter, because chances are that if you have teens hanging around your business, they probably spend money there and you're going to have to interact with them.

    And as for whether this bothers teens immensely, I call bullshit. Most of the older TVs out there put out a high pitched noise and it isn't like teens don't spend a ton of time sitting in front of one. Of course, old people enjoy buying crap like this, so it isn't to say there isn't a market.

    Also, the sensitivity seems to go away after being exposed to the sounds of gunfire (anecdotal evidence based on my experiences, so take with a grain of salt) and other loud noises, so gangbangers and punkheads probably won't be affected ;)

    I frequently whip out my tone generator in class and put it at high frequencies very loud. Gets hilarious when half the class is yelling about a noise and the teacher thinks they're crazy.

    On another note, would those neat Bose active noise cancelling headphones remedy this problem? I know it's rather easy to build active noise cancelling headphones, and if this happened anywhere in my town I would make pairs of these for everyone just to spite them.

    Also, I tend to have worse hearing than most of my peers due to the fact that I play drums rather extensivly. Would this stop me from hearing the sound?

    This just looks like an ultrasonic animal repeller to me. Here's an easy Google Search [google.com] that shows how common they are. The thing is, anyone with decent hearing will hear these ultrasonic devices too -- and yes, they are extremeley irritating, to the point of being painful. My parents live way out in the country and use one to keep deer away from their garden, and another one to keep their neighbor's cats away from their parked cars. Having to suffer around 2 of those things any time I visit my folks, I can easily recognize the high-pitched agony-inducing devices now.

    And as a result, I suspect there is a powerful one in use at the Huntington metro station [wmata.com]. It's cranked way up, frankly to the point that I worry about hearing damage when I walk through the protected area. I can hear the sound just inside the entrance, aimed right at the turnstyles (slightly stronger at the side near the fare card machines). In this case, I imagine they're using it to keep birds and squirrels out of the station. The station itself is in a surprisingly wooded area, nestled into the side of a small hill. I'm sure they found an ultrasonic animal repeller was the only thing that worked at keeping critters out of the station. It nearly keeps me out too ... it actually makes me feel slightly nauseous if I hang around in that entrance area too long.

    It's easy enough for me to create a home made high pitched squeal. Just take the phone away from my teenage daughter. From what I have been able to ascertain, the telephone is permanently attached to her ear. Taking it away causes her physical pain which results in her emitting an extremely loud high pitched squeal.

    I try not to do that anymore because the neighbors complain.

    I belong to a club that's made up of mostly seniors, so I'm one of just a few people there under 40. A few years ago (I was 25 or 26 then) I was playing with one of our long-time members when I began hearing this really high-pitched whining noise, right on the high edge of my auditory range. Wasn't super loud, but definitely loud enough to notice if you could indeed hear it. After determining to my satisfaction that I wasn't crazy, I deduced the noise was coming from some definite source. I asked my opponent if she could hear it, and she said no but wondered if it was her hearing aid. She turned it down and sure enough, the noise went away! Apparently I was the only one who could hear it.

    Two more occasions I heard the noise and immediately asked her to turn it down and it went away, so that pretty much confirmed the first time wasn't a fluke. I dunno exactly what was happening, but I figure the hearing aid was generating feedback when turned up too loud. After all they are just compact microphones and speakers.

    I tell you, when I heard this noise and I couldn't figure out what it was, I started to get really agitated. The agitation was to the point that where if someone heard it for a sustained long time they could seriously go insane or even try to kill themselves. It was bad. The sense of relief I felt when the noise was turned off was quite profound.

    So anyhow, I didn't RTFA but if they're talking about using this device on a long-term basis to keep teens away from somewhere, this is tantamount to torture. I think anybody considering using this for anything other than security in imminent danger (e.g. teens harassing you) deserves to lose the rest of their hearing too.

    A cinema in my town had the same problem with large groups of teenagers loitering at the entrance. Once they started playing nice classical music (not even loudly) they all dissappeared. I guess it was no longer a "cool" place to hang out any more. I think the makers of this device should have tried their first option, at least it's less iritating to customers.
