There is some oscillation at different frequencies once you get up around 8KHz that reminds me of BFO from old shortwave receivers, and that's confusing.

If this little test is near accurate, I've recently lost a little more in the high end, since I go out after 10KHz. Just a few years ago, I was fine to 13. Also have to wonder what YouTube's high compression is doing to the audio.
