I had an audiogram today as part of a medical assessment for a job this summer. It was pretty neat! They would play a ringing or buzzing noise in one side of a pair of headphones and it would get steadily quieter; I had to press a Jeopardy-style button every time I heard the noise. I'm not sure how well I did, but I could hear some of the faintest noises. It's kind of strange, but some noises are so faint that you can feel them more than hear them, if that makes sense.
Maybe I was a dog in another life. That would've been pretty awesome. Sleep all day and get tummy rubs, aww yee.
