Nobody is Listening to the Modern Hearing Problem
I can't hear the tone, though somehow it manages to set my nerves on edge, anyway.All this is fun and games, but no one seems to be concerned about the health issue this has revealed. There is natural age-related hearing loss, called presbycusis. And then there's unnatural, accelerated hearing loss from noise. Most 30-year-olds should be able to hear a 17-kilohertz sound. This is the case in quiet societies in remote regions such as Nepal and parts of Africa. The fact that many of us cannot hear the Mosquito is a result of an epidemic of noise-induced hearing loss, not just aging.
