For several months now, i experienced a ears buzzing all the time.  I was about to get my ears checked when I decided to wait until I come back from the cruise , I was going for a week. To realize that while I was on the ship , I didn't hear anything.  The answer was clear and loud. Those towels frequencies make a lot of damage.
