This is the most common type of tinnitus. It can be caused by ear problems in your outer, middle or inner ear. It can also be caused by problems with the hearing (auditory) nerves or the part of your brain that interprets nerve signals as sound (auditory pathways).
Mine started from gunfire to close to my ear in Vietnam. I was told that caused damage to the ear's cochlea called the organ of Corti, the sensitive hairs are small sensory cells that process and transmit sound to the brain. I agree with medation or outside activity, bike riding, reading, music, many other things help me. 69 year old male!
