The disorder is often associated with a hearing loss. It can sometimes develop with the use of some medications. Check with your doctor or pharmacist, if you suspect this problem. For the most part, though, tinnitus is associated with inner ear problems, such as Meniere's syndrome or exposure to loud noise. Noise levels are now carefully monitored and controlled in most industrial settings, so a lot of dangerous noise levels are found most often in recreational settings.
Prevention seems to be the key to dealing with the problem.
There is no generally agreed-upon medical or drug therapy that can be offered to eliminate the noise, and there is no surgical option. If you have a severe case of tinnitus, some strategies may help. In many cases, treating the hearing loss by using a hearing aid will cut down on tinnitus. You may want to try turning on the radio as you go to bed, to mask the noise. You can also try using an electric fan or a white noise generator.
