    bah they modulate the tone itself, that's perfect. if you play a 16khz sound right next to it - or even in the neighbourhood- it should sound pretty damned funkie. Give it a shot: mix that file by thedialogueproject with a straight 16khz tone and see what happens.

    of course I could be wrong.

    if that fails mix it with a 16khz + something tone (dobroide could you figure out the actual frequency of the higher pitched part?)

    Bram,
    I did what you say (assigned separate channels to the original tone and the one generated by me) then played together and... it sounds like crap smile As for the high part actually it's 16500 Hz, click the thumbnail belo for a detail

    Hi,
    Rode NT4, AT822, and Soundman OKM binaurals are popular choices. Search the forum around, there are several threads about the subject

    play another signal with a frequency very close to it: by SLIGHTLY modulating the frequency of the second signal you can modulate the first and make it thus hearable for EVERYONE.

    that's actually a very good experiment. can someone please go figure out what frequency this thing is at?

    - bram

    according to thedialogueproject, 4 kHz and 16kHz. For spectral images see my comments here:

    and here:
    http://freesound.iua.upf.edu/samplesViewSingle.php?id=48258

    About fighting the thing... I'd wish to know if the shop warns visitors about the sound they are being exposed to. And it might be interesting to ask a lawyer about the legality of the technique. Taking actions againts the shop would be a nice way to fight this,..

    Any recommendations at all for a stereo mic?

    i wonder what would be the best way for the individual to combat this type of thing?.... ear plugs? ....cut the wires? ...somehow aim another frequency at it and cancel it out? anybody?

    @ dobroide: sure! But my recorder is broken down and still saving money for a new and better one so it may take a while. But I'll record it for sure.

    PS: For those of you living in the Netherlands and curious to experience it: the mosquite is in use at the Rijnhaven and Maashaven metro stations in Rotterdam and at some other spots in Charlois (Rotterdam Zuid).

    LG, would you record it sometime and upload, please? I'm curious...

    Yup - the mosquito. This device has been in use since quite a while at different locations in my town. While I agree that sound as a weapon is awful I can't deny that it is functional to keep public places slightly more public. Let me try to explain this. You see, some areas such as metro stations or obscure squares have become the habitat for certain youngsters. This is nothing new and young people should have a place to hang out. But at the spots I'm talking about the groups grew bigger and bigger and their behaviour towards others became very aggressive. So the public space turns into their territory and becomes less public. You know there is something wrong if people don't want to use a metro station anymore.

    So, that device was installed. And the groups dissolved. I'm not saying they seized to exist but at least they didn't move to another place together as a group. The devices are installed at places (e.g. entrances) that other people ususally don't stay for a long while so it doesn't bother people passing by. It is only bothersome to people who stay there for a long while. Also, the mosquito has fairly short range so it is rather local.

    Altogether: yes I understand your feeling but at the same time I have to admit it is functional in some places.

    By the way, some elderly complained they could hear also the noise. I couldn't.

    This device is the complete antithesis of the freesound ethos and that of all freesounders - it is sound as weapon. An assault on the human condition and also a perfect example of corporate greed over-riding normal values. The device will solve an immediate local problem by moving people on but this does not make them disappear - they just take their problems elsewhere.

    What about this for a solution - the under 25's themselves should make a vow never ever to use the shops or companies using these devices as long as they live and their families and friends should do the same. A bit of direct action - and a boycott will hit them where most of their feelings are - in their pockets.

    I agree - this is barbaric.

    The story has only really just broken in the UK. And if it is indeed making kids lose their hearing in these frequencies, it's nothing short of abuse. Would love to hear from anyone with technical knowledge in this area.

    Thanks for the posts. Let me know if anywhere else in the world is suffering from this extraordinary display of adult ignorance...

    (By the way - kids are using it as a ringtone on their phones so adults can't hear it.... Seriously.)

    thedialogueproject,

    that is a very distressing post.
    you should take it up with the media - because this is reducing the time your kid will hear these high frequencies.
    basically, they are making your kid deaf - in the higher frequencies.

    it's interesting to say the least... but to digress a bit.... i wonder what the precise frequency is that the ATF used in waco, texas? anybody know what i speak of? i know it is low frequency and that it supposedly caused fatigue and sickness. (i need to start a thread about "sonic levitation"wink :twisted:

    I'm 17 and here in Qu├ębec shopkeepers don't use it (yet) as a teen-repellent. Teenagers use it as a stealth ringtone instead. smile I agree this is very barbaric. The unconscious people that created this product don't even know what this sounds like. It's hear-splitting, and if all shop started playing this in front of them, it would be a very anti-social act, even more anti-social than the supposedly delinquant teens.

    What exactly do you mean by grimey? Name some artists. I suggest buying a crate of old-ass vynils and start digging, if you have the same grimey as me in mind.
