anybody here about this ringer called mosquito?
apparently someplace in england there was a shopping center that was frequented by some rough youths, and the adults didn't like them hanging around. so they emitted a very high frequency that adults can't here, but youths can. and it's highly annoying.
whatever the story, i have it on my phone. so today in lab i set my ringer to mosquito and i was able to test without my professor knowing.
but my lab partners got really annoyed.
