Most anti-loitering devices are focused at teens and young adults. As we age, we lose the ability to hear the right range of notes. Therefore, young people can still hear a high frequency buzz that adults would not even notice. There are several problems with these devices. First of all, the device is targeted at a very narrow audience. Another problem is that it assumes that all older people will not be able to hear it. This is not necessarily the case. The device projects the sound at a wide range so the chances of upsetting the neighbors as well as deterring loitering is a real possibility. It also assumes that it will only effect its teen target audience. Many animals can also hear high frequencies. For instance, some areas have been forced to remove the device because it upsets the neighborhood dogs. Some suggest that the device can actually damage hearing, although this has not been proved. Such a device could certainly be useful to some businesses, but the right situation is certainly necessary.
