So you know of that mosquito ring tone that is stirring controversy? Well I went to a website that played it

http://www.teenbuzz.org/

Here you can see categories of frequencies that you are supposed to hear. The highest frequency that I can hear is 14 kHz (45 years and younger), which means my ears are bad for my age =27.

I'd be PISSED if I had to put up with that and I would never patonize businesses that had that noise device.
