I've always wondered about that. I'm also bothered when walking around Tokyo (it's very prevalent in Ginza for some reason). I've also seen it in other cities in Japan but I've never had that issue in other cities in Asia (Hong Kong, Shanghai, Bangkok, etc..) I'm 40 too but as a kid, I was very bothered by the high pitch wine of the tv turning on, so I'm guessing I've always been rather sensitive.
