1. Bill Clinton
After years of exposure to loud rock music and noise from hunting rifles and political rallies, former President Bill Clinton experienced difficulty hearing in noisier environments. During an annual physical in 1997, he was formally diagnosed with high frequency hearing loss and fitted for completely-in-canal hearing aids. Clinton and Ronald Reagan were fitted for hearing aids while in office, which provided a positive spin to the usually negatively-stereotyped hearing aid.
Fun fact: Bill Clinton aced a radio show quiz about My Little Pony: Friendship is Magic!
