I've had it for several years also. The volume of the crickets/locust comes and goes for me. Worse in my left ear. Just like all of you have said I sleep with a fan which helps a great deal. Over 30 years in a power plant and lots of loud R&R in my youth. I didn't have sense enough to wear hearing protection in my younger days. I wear it religously now even mowing, weedeating or using the tractor at home. I'm sure it will get worse as I get older.Not a pleasant thought.
