Most commonly refer to that sound as “receiving downloads”. When it comes as that tinnitus type sound (which is like tinnitus but is different), it usually means the download you’ve received will unpack with it’s meaning delivered at a later divine time.

that’s how I look at it anyway. I’ve had incidental tinnitus earlier in my life after a day of using loud using power saws. If you’ve had both, then you can tell the difference between them.
