It depends on the person. By the time I > finished high school, I probably couldn't hear anything above > 15KHz courtesy of loud hard rock music. I wouldn't be It works the other way too. I lost a lot of my high-frequency hearing at one rock concert at age 18 (was pressed right up against the speakers and didn't know enough to stuff my ears with tissue.) Now I'm 37. I can't make out voices if I'm in proximity to running water or other white noise in the same frequency range, but I can still hear really high-pitched whines like the ones CRT's and some security systems make. I'm sure there are other adults who'd be annoyed by this thing too. That said... ear buds and/or spray paint, totally. Not that teenagers who are loitering are likely to be wearing ear buds while they talk to each other, nor are they likely to escalate to vandalism, but those are options. Much as some people would like you to believe that teenagers behave like insects or rodents, they never have and probably never will. That device and its site are comical. As far as I can tell, the biggest change that's come about as a result of its existence is that teenagers now have ringtones that they can hear and most adults can't: http://www.npr.org/templates/story/story.php?storyId=5434687 But who knows, maybe the next time I go to the mall in a year or two maybe I'll hear "eeeee, eeeee, eeeee....."
