I can't but i think i'm glad.

I cant hear any alarm and I am 23

[Fishcake]

23 but with the ears of a 25 year old, if there's a sadder tale to be told i haven't heard it.

28 and I can hear it

28 and I can hear it

28 also and i can't hear it at all.

I can hear up to about 14Khz "Some adults most teens" on here

[iPrank]

I can't hear the hidden alarm in the song.
But I can here the ringtone upto 20KHz.

And I ain't no teenager.

I can't hear it or smell it, and i'm 19

[thegreatone]

Can hear it, and thats probably the worst music i've ever heard. Doesn't hurt my ears though, so why would it be marketted as a deterrant?

[timeshifter]

I could hear the 17KHz, and I could sense the 18, but didn't actually hear it...

[iPrank]

BTW, that 20khz sound gave me a headache. They should name it 'adult repelant'.

[Andrew G]

I finally heard 18khz but from one ear only

Can anyone hear the Brown Note

[eSPiYa]

I'm already 21 but still can hear 20khz.
Does this means I'm still teenager?

I get up to 18 khz and 17 years old...damn you guitar

Try reading the news piece
The sound is emitted at known trouble areas because only teenagers can hear it. The sound is painful so it stops the teenagers from hanging around that area

Pretty effective too

I couldn't hear it, but the voices could. THey say it's awfull...

[timeshifter]

I get up to 18 khz and 17 years old...damn you guitar

Hadn't thought of that... maybe that's why I can only get 17khz... all those pressure harmonics slowly melting my ears...

[iPrank]

I'm using a good headphone. Maybe that's why I'm able to hear 20khz.

I'm 17, doesn't hurt my ears at all!

Hence why i'm wondering why they reckon it's effective.

That sound clip says "kill them all, kill them all, kill them all, ..." in a loop.
