This is so cool
Go to http://www.ultrasonic-ringtones.com/ and se what you can hear. Viv and I can only get to 12000 and can't hear 14100. David can hear 17742 and leaves the room when I keep playing it. But it doesn't bother us at all.
Viv and Ian:
You're in a mid life crisis |
Your ears aren't what they once were and you have resorted to doing online hearing tests. The highest pitched ultrasonic mosquito ringtone that I can hear is 12kHz |

David:
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 |
