@jamino I agree that AI would be helpful, but their are over 50 medical tests beyond a MRI or CT that may be needed to be used to determine the exact nature of one's physical tinnitus. There are also some methods and treatment that can help some with tinnitus from hearing loss.
A large percentage of those with tinnitus also have physical input. All of the physical inputs are known to researchers. There's a few things that can greatly have involvement to someone that already has tinnitus. Of course loud noise is high on the list, but also is forward head bending and posture. Posture would also include mouth movements. The immune systems also plays a big role as infection and bacteria is not a friend for those with tinnitus.
