I had a pretty brutal headcold a few years back and for about two weeks afterwards I had what I described as "supersonic hearing" though my doctor called it tinnitus.
I could hear my neighbor's garage opening a block away in San Francisco and had a frequency sensitivity that was totally abnormal. It was also really painful so I'm glad I got my normal hearing range back.
