in reply to What's that noise?

"Sinus" is the only tinitus type answer allowed?

I've got three forms of the damn thing, popping from sinus from time to time, clicking from going on a plane with a flu and hurting my ears on the decent, and two or three ( really annoying ) high pitched pure tones from load concerts...

So... that noise is mostly in my head.
