I read about a machine that is developed with an aim to keep teenagers out. The machine emits a sound that’s really annoying especially to teenagers. It’s called ‘Mosquito’. According to the inventor Howard Stapleton, that high -frequency pulsing sound can be heard by most people younger than 20 and almost no one over 30.
I think it’s ridiculous to keep teenagers out...grow up people they are not animals who’ll run off with a whistle. I think they are intelligent enough to know where to go and where not, they do not need these kinda machines to shoo them off.
