Can you hear this?

[Jayhawk]

"Jesus Christ!"  was my reaction, of course I forgot my volume was turned up so loud.  Under 25.

The 25 is just a generalization, different frequencies will vary for different people.  I seem to be particularly tuned to the frequency from a television, I can tell when one is turned on or off with my back turned or from a different room.  I remember back in elementary school, when returning to the classroom, we'd be walking down the hall and as soon as I passed the point where the wall to my classroom would be, I could tell if we got to watch a video that day!

There are different ones, different levels.

The sound of the one in the OP website sounds like the one that is about 49 years or so.

I can hear them all, barely the first one, but I can hear it.

I can hear 17.4 (if I concentrate) and up... anything under 17.4... NADA.


I'm 34 almost 35

I could hear it. Im 21 with moderate/severe hearing loss.

[Meatwad]

I have one on my cell phone that I've never found an adult that could hear it. I'll see if i can get it posted on here and see what its like for ya'll.

Id be interested to hear it.

For the test... used the same audio setting on all clips

8-16K heard fine
17-20K could tell something was there, made my hearing senses tingle. Max out volume and then I could hear it.
21-22 heard but was lower pitch

[Nwbie]

54 - heard it

I have dang near perfect pitch so I hear most sounds no problem for some reason

They have this sound outside one of the local grocery stores to keep kids from loitering.

I do not understand why anyone would use this as a ringtone to avoid teachers from hearing it... Just set your rington to vibrate and you will be the only one to notice

43 and heard it loud clear and annoying. 800Nate has nothing on that sound.

Ha, i have to disagree with that, vibrate on many  phones is so aggressive it can be just as noticeable as a full ring, worse yet everyone might start looking around trying to figure out what that humming is.

37 and heard it.

The following link takes you to a website where you can play a noise that only the "young" can hear.

Apparently people older than 25 can't hear this noise.

I have seen this on the news and was always curious about it.  I saw some report where they pipe this noise over speakers to discourage teens from loitering.

Thing is i'm pushing 40 now and I can still hear it.

Can y'all?

(say if you over/under 25)

(edit: was googlin' this and found an interesting article where Teens are using this tone as a Ringtone for their cellphones because adults can't hear it.  They can be in class and get a phone call and the teacher can't hear their cellphone ringing.  Clever.  Link to Story about it
