Here’s a website that can generate tones. If you enter “3800” into both the left and right ear boxes, that’s what I hear 24/7.

Is that about the same for you?

I entered 3800 into both left am\d right. Pressed “Play.” Heard nothing at all.

Ah. No earphoned on my computer, just a sound system.

Best I can tell. Right ear..10000, Left ..maybe the same.
