Download Mosquitotone: Teenage Repellent turns favorite Ringtone of Students

That's strange. The one from the BBC just sounds like ambien background noise with a girl laughing. However, the other one from the the NY times sounds like a loud ringing. I'm 25 years of age, so I suspect I should be able to hear the tone. I played the NY times version to my mother who is over 50 and she could hear the loud tone too.

Are you sure this is the correct sound for the 'mosquito tone' for teenagers only or an example of what is supposed to be heard by adults and children?

There is a high pitched ringing in the one from BBC, it does have ambience in it also.

I am 24 F and I can hear both. I've heard that noise before too thinking my ears were just ringing from the mall being too loud- I now know better. Also my local radio station played the ring tone over the air which I though was loud and annoying and my 49 year old mother heard nothing. As for teen deterence in shopping areas- they better be careful as not to deter those older shoppers who can also hear the noise.

only young people can hear the proper noise - this is just a recording not the real thing um at my school 2 in 6 teachers can hear it . old people wouldnt be able to hear it as there hearing is not as sensitive as young people

Im 14 and i cant hear anything. when i open it in my sound program it shows no sound in the file. this is a fake.

I have herd this sound before. My Big screen TV make this sound when it is plugged in. At night I have to unplug it just to get to sleep.

Question, why would only males be able to hear this sound?

Hey this dont work every 1 can hear that sound of laughing & then two beats!.

Nice way to get protection from mosquito.It is really effective.

ankit you idiot the laughing and two beats is normal sound...the "secret" tone is an ambient ringing you should be able to hear

Just to help others, the first link dosent work right. right-click the Mosquito Tone Mirror link and choose save as.

Lots of people older than 25 can hear it too. It's annoying, like the whine from CRTs. I am in my 30s and can always hear CRTs (including TVs and oscilloscopes) from a long distance away because the high-pitched whine travels a long way. If malls use it, I won't shop there. The whine is too annoying. LCD screens are more of a blessing than deaf old people realize!

Sorry guys but I am a 35 year old male, a school teacher and I can hear that perfectly well. One of the girls in school today played that ring tone in the class to check if I could hear it. And of course I can. And it’s annoying! I felt very uncomfortable hearing that broken television sound. She was surprised. And this year 11 told me: You shouldn’t be able to hear it!!. Well, I do and I’ll be very uncomfortable to have to hear this under-25s repellent anywhere to be honest. WE NEED FURTHER RESEARCH HERE. I THINK.

The second one older people can hear my mother is 34 years old and just got angry when i played it!!!!

I'm pleased to hear that I'm not alone when it comes to being an adult (32) & suseptable to high-frequency sound.
To be honest, the Mosquito isn't that high-frequency compared to other sources. It's still an awful sound, and the one I've come across in my local area made me feel like smashing the thing coz I felt as if it was invasive.

CCTV cameras emit a sound also, as do flashing LED's, Cathode-ray tube TV's, Satellite Dishes (by far the highest frequency & although it's quiet I am aware of every sky dish I go past fixed to peoples walls as I walk down the street). And as for those cat-scarers people put in their garden......... scrape yer nails down a blackboard & that gives an idea of what they sound like.

So.......... the Mosquito gets a thumbs down in my opinion, coz it's far too invasive & rather than being a deterent to me anyway it makes me get angry & feel like smashing the source of the torture.

I (37 m) have also heard this, online and at a local mall, but already knew what it was due to earlier articles. My wife (28) can't hear it at all.
I've complained to mall management, but was told that it seems to work (they showed a report indicating a whopping 2% reduction in shoplifting since they started playing the tone... ignoring the fact that they started in September, when most of the "targets" would have been in school anyway. I just stopped going to that mall.

Can't hear it my BUTT!!! I'm 38 on the outside and it PHRICKEN HURTS!!!! How the heck can you NOT HEAR THAT???
