Parks and Recreation Centers Are Using Sonic Devices That Play High-Pitched Noises To Repel Teens (npr.org) 406

NPR reports of the various parks and recreation centers in North America that are using sonic devices to repel teens from the premises. Philadelphia, for example, has 30 parks and recreation centers that are outfitted with a small speaker called the Mosquito. "It blares a constant, high-pitched ringing noise all night long -- but one that only teenagers and young adults can hear," reports NPR. "Anyone over age 25 is supposed to be immune because, basically, their ear cells have started to die off." From the report: Philadelphia parks officials have been installing the device since 2014, reported WHYY's Billy Penn, intending to shoo rowdy youths from the premises. And it's not the only U.S. city to do so. Mosquito's Vancouver-based manufacturer Moving Sound Technologies works with roughly 20 parks departments around the country to implement the youth-repellent devices, says president Michael Gibson. It's intended to prevent loitering and vandalism by teens and young adults at public facilities. But some say this age-based targeting is a form of prejudice. Philadelphia City Council member Helen Gym refers to the devices as "sonic weapons" -- and she's working to get them removed.

[I]n Philadelphia, Parks & Recreation defends its use of the Mosquito, saying the devices are operational from 10 p.m. to 6 a.m. only, and they're just one part of an overall anti-vandalism strategy that includes fences and gates, security cameras and night watch staff. For now, the city is moving forward with installation. Despite the backlash, two new Mosquito devices are being installed at other city playgrounds as part of major renovation projects.

    Seriously, Midnight Basketball? You _want_ those kids at the parks. Kids out late at night without parents aren't doing that because they're evil or something. They've got problems at home. Either parents that don't care or care but work non stop. They should have a safe place to go.

      Yup. Repelling kids from something that would keep them entertained and occupied is going to do the opposite of make things better overall. It's sure as hell not going to reduce vandalism; if they can't hang around relatively harmlessly at a park or recreation centre, they're going to wind up going somewhere else and definitely vandalising something else.

        I think the entertainment value they get from breaking into a park or rec center when it is closed is something we can reasonably deny them. And saying we can't chase them away from vandalizing the rec center because they'll go vandalize someplace else is, well. silly.

          OK then, how about this:
          Those devices repel ALL teens. The rowdy ones as well as all others. This is a form of discrimination based on age. Also, at 25 you are no longer a teen, but a young adult.

          Furthermore I see you make an incorrect assumption: "breaking into a park or rec center when it is closed" - which is untrue. The parks are NOT closed, as a matter of fact I am wondering if public parks are ever closed. Certainly not in my country. So this means that between 10 PM and 6 AM, a certain category of people is banned from entering a park simply due to their age range. Oh, yes, my girlfriend is almost 39 and she can hear 12 KHz sounds (I cannot).

          I'll add one more thing, based on personal experience (and yes, I know it's rare but it happens). My oldest child had belly aches when he was a baby, especially during night. So what I did was put him in his baby cart, take him out and walk him through the park until he fell asleep. Now imagine those bloody devices having been installed, my baby having been able to hear them, but me being completely oblivious to their effect.

            Firstly that's a non-sequitur statement. Secondly if some kids are in a closed park then they are by definition rowdy law breaking brats. Up the volume.

          I grew up in a small town with very few entertainment options, and very few of us had money. For us, the public park was the "hangout" on weekend nights. About 8pm, cars would start to show up and basically the population of the entire highschool would be there by 10. There was drinking and fights, you are going to get those just about anywhere a bunch of teens hang out, but for the most part, it kept us from getting in to trouble.

        "Anyone over age 25 is supposed to be immune because, basically, their ear cells have started to die off."

        The fact that adults can't hear ultrasonics doesn't mean they're not affected by them. A significant subset of adults will, in the presence of ultrasonics, eventually experience nausea, headaches, tinnitus, and a variety of other unpleasant symptoms (it varies a bit by individual). Problem is that the effects aren't obvious immediately, they can take up to an hour or more to be felt, so it's a bit hard to make a case that it's the ultrasonics causing them. The discrimination angle is probably more likely to be successful in getting this nasty stuff banned.

        And to the cretins who decided this was a good idea, their punishment should be being locked in a room for twelve hours with strong ultrasonics.

In the USA parks are generally closed after dark, and don't open until dawn or thereabouts, so it is indeed trespassing. Such regulations come about because we need them, given the ongoing tearing of the social fabric. Those regulations are there to combat problems, and most of those problems are even real.

    If you're only using these at time when the sites are supposed to be closed, and you've also thought through the other impacts, then it shouldn't be a problem, but I don't see it being as limited as that.

    Since NOBODY is supposed to be in the park after hours, why not painfully loud klaxons to drive all ages out of the park? Perhaps the security alarms designed to make people feel sick and disoriented. Add painfully bright strobes to make sure the deaf can't sneak in either.

      Since NOBODY is supposed to be in the park after hours, why not painfully loud klaxons to drive all ages out of the park?

      There's actually a practical reason to use high-frequency sounds for this purpose. The atmosphere absorbs higher frequencies more readily [sengpielaudio.com], meaning higher frequency sounds become inaudible (assuming your ears can hear the frequency) beyond a shorter distance. It's why foghorns are low-pitched - the low frequency maximizes the range at which you can hear the horn.

      So the noise from broad-spectrum klaxons would travel very far and cause noise complaints in neighboring communities. But high frequencies will attenuate enough that they're indiscernible after a few hundred meters.

    Palm Beach in Florida may lead the way in insane electronic warfare on segments of the population. They started with very loud opera being played in a public park all night long to keep the homeless from sleeping in the park. Now we see cities that consider teens as the same social losers as the homeless and sound is again the weapon to keep them out of a park. The really sick part is that in the case of the homeless the state essentially orders the homeless not to exist. They are not allowed on either public or private property which I suppose orders them to turn into vapor and float around in the sky. somehow the homeless simply refuse to not exist.
