Have had ringing in both ears since very young. Cannot hear many of the common "beeper" tones used in everyday things (4 Khz) . It gets A lot louder with exposure to certain foods, cigarette smoke, diesel fumes (exhaust) etc. look into your environment/diet for triggers pay attention to volume. Avoid things that make it worse. Learn to tune it out. Pycnogenol (Maritime pine bark) daily at 50-100 MG. also helps.
