We’re not too sure what something like the Sonic Nausea device is doing in the open market – shouldn’t stuff like this be banned? After all, the rather deadly combination of high frequency soundwaves that will result in the majority of people who hear it to feel queasy or suffer from headaches, intense irritation, sweating, imbalance, nausea and vomiting sounds (pun intended) as though it belongs to the military or riot police and not in the hands of pranksters. To make matters worse, the nature of its sound makes it all the harder to track down if the device is hidden. Perhaps the 9V battery which it is connected to will be able to provide enough juice to run for hours on end – making it the ideal tool to have everyone in the immediate office feel sick to call it quits for the day. This $29 device could be a practical joke pushed too far, don’t you think?
