I am not affected by the mosquito as an oldie, with ears that are unable to pick it up. Even so I do not think that it is right that the young get blasted by this noise. What about babies and dogs. This will only create more noise. It might also be against the young citizens civil rights and not all are trouble makers. The fact that oldies cannot hear it does not mean that it violates noise pollution laws.
