Ultrasound ringtone only teenagers can hear!

June 25th, 2006

Back in April, an untrasound device was installed by a Theatre Square in the UK in an attempt to repell young trouble makers. It works by emitting a very annoying high pitched sound which can only be heard by young people. This is because most adults gradually lose the ability to hear high pitched sounds.

While this has proven effective in repelling yobs from the theatre square, it has also been exploited by teenagers as a ringtone which their teachers will not hear in class.

To find out if you can hear the ringtone dubbed the Mosquito Tone, listen the mp3 file here:

This has also been featured by the BBC and they have an audio clip (Real Player) demonstrating the use at the theatre square.

    Probably means you got brilliant hearing! Do you find it to be a very annoying sound by the way or is it just a sound you can hear?

    27 going 28 rather fast, but I could hear it. Kinda annoying, high pitched beep, but after about a second or so, my ears started to filter it out…

    Can I download it for my mobile phone? From where?

    If your mobile phone supports the use of mp3s as ringtones, you can download it here and then transfer it to your phone.

    Ok, this is going to sound hard to believe. I am 54 and it hurts the heck out of my ears. I think it is a “middle C” on the piano.

    I am a musician. Maybe this is why?
