I agree w/elizabeth could be sinus/middle ear related. Since I was 30-something I have had allergies year-round where I live (tree and grass pollen) and it definitely affects hearing. I take Loratadine daily and it seems to help.
Barometric pressure, temperature, moon phase?
I’m off work tomorrow, made sausage and peppers for dinner, and now I’m enjoying a Sazerac on a beautiful summer evening, listening to Joni Mitchell. All is right with the world, at least at my house. But... the stereo sounds ever so slightly, not quite there. It did the other day, but tonight, it’s missing some tiny bit of something. Has this ever been experienced by any of you out there? One day magnificent, another day, just ever so slightly not quite as good. Atmospheric conditions? Mood? Magnets? Thoughts?
