Can there be another cause for tinnitus increasing other than sound?
Stress can often make tinnitus increase especially in the first few months. Please read my post: New to tinnitus what to do, for more information on this. Tinnitus comes in many forms and no two people experience it the same. You have said you've read many of my posts? Therefore, you may remember me mentioning silent rooms and surroundings are not good for tinnitus especially at night. It is a good idea to use low level sound enrichment whenever possible.
Another thing I noticed the other day is I had this head buzz which was really annoying but I could straighten it out and make it more tonal (less annoying) by listening to some sounds on reSound. Have you come across that before?
Tinnitus can fluctuate a lot in the early stages which you are in. New sounds are often experienced too but with time the tinnitus will settle down. It is something that you have to be patient with and work through it.
