Just thought I'd post this as it was quite distinct.
I had a very clear Left ear tone, 21 seconds, slight plug, north facing, at 2:15pm on Saturday, March 6.
Using Petra's formula, 21 seconds would be for 787.5 miles away from Portland, Oregon within 10 days.
Possibly for something North and/or West of here.
The frequency was one note higher than A 440 Hz, or "B".
Not super loud, but not at all quiet either, so I guess medium loud.
