Remember how some shops are using ultrasonic tones piped outside to discourage teenagers from gathering in large groups in front of them? It looks like the teens have turned the tables and are now downloading the ultrasonic tones to their cell phones so they can take calls on the sly while in school. I wondered if I would be able to hear the tones, so I took this quiz.
You are the typical teenager
You can hear the frequency of the mosquito teen repellent – but probably not for much longer!The highest pitched ultrasonic mosquito ringtone that I can hear is 17.7kHz
|Find out which ultrasonic ringtones you can hear!|
What is the highest frequency you can hear? Thanks to John Scalzi over at Whatever for the links.

17 was the highest I could hear, although I ran all the cats out of the room with the higher ones. lol
I need to try that later when it’s quiet. My friend says I can hear a cockroach’s heartbeat.
Dude, all those cymbals crashing in my ears and base drums have taken their toll… Sigh. 16.7
Oh dear, 12kz for me
I got the exact same as you. Some of them actually hurt my ears.
