I believe this ringing might have something to do with unity consciousness downloads as taught by the scientist Carl Calleman.
As we raise our vibration the body will begin to undergo subtle changes. This ringing, much like the human emotional system, is added to our skill set as an additional indicator or spiritual compass for us to use at our discretion. Much like fear is an indicator or a low vibrational thought, and love an indicator of a high vibrational thought, the sound in the ears seems to get louder as we approach the thoughts/learning required for our personal ascension.
