Within the first couple of weeks the almost constant "Jet Roar" was gone. It turned into a loud hissing noise that fluctuated. After about a month, the noise level went down, still fluctuating. Some days I had it, somedays not at all.
It almost went completely away. Now that the muscles in my face have relaxed and most symtoms are gone or almost gone, it only comes back when I'm stressed or tense. It never comes back as bad as it was. It's tolerable.
With the back problems I've had and especially with my Mother's health declining, the days I get really nervous and worried (stressed & tense) it comes and goes.
When I realize I'm hearing noise, I also realize I have my facial muscles tensed.
In my case, I absolutely believe it's muscular, as I was told. I decided yesterday to start wearing the splint longer everyday, since I am in a tense situation most of the time right now.
The splint I have, relaxed muscles in my face (very quickly) that had been clenched and in spasm for years. The worst of the Tinnitus went away.
I have to remember that years of habit, consciously, and factors that I had no control over had caused this problem. I assume it will be an ongoing process to learn "not" to tense up my facial muscles with stress.
Even with stress, the noise has not come back to untolerable levels that invade my life and drive me crazy.
If Tinnitus is caused by muscle tighness and spasms, it can be contolled or go away completely.
To answer your question, I had very little noise after about 2 months.
I hope this helps you,
