The other day my dad, who turned 60 last year, swore he couldn't hear a cicada that was right outside the open window. It bugged him so much he made me go outside with him and point out the cicada. I told him about the mosquito tone, which is obviously much higher, and how mostly only younger people are meant to be able to hear it and played it for him off Wikipedia. He could hear it fine and so could I (30 this year). To hell with the mosquito tone as an anti-loitering device, it's horrible.
