Yeah I have it, Stress and diet will affect it someone above mentioned "excessive amounts of real salty foods like potato chips, pizza, caffeine (diet Coke)," Chemical additives in these foodsincrease the problem, so does alcohol and smoking. There is all different sounds people can hear however usually it's a high pitch. You can turn it down if you try hard enough its adjustable through breathing. Stress is the worst for it so lighten up improve your health and only do whatever the 'voices' in your wifes head tell you to do...not your own.
