Neat! I could hear 11, 12 and 13 clearly. After that it's faint but still
audible, but only up to 16. I had the speakers up all the way when I
started being unable to hear it, and probably ****ed off the cats.

Thanks everyone who suggested a hearing test. I will do that. The rest of
the conversation has been interesting, too!
