Mikey will answer later but I have direct experience and background knowledge of tinnitus. (Incidentally I was involved a while back with an individual who claimed a similar explanation for autism, that it was down to a 'connection with spirit'. I later discovered the guy was desperate to find a spiritual cause for his own tragic issues.) Tinnitus is suffered widely in our population - check out the BTA: https://www.tinnitus.org.uk/. Its causes are several and of a physical/biological nature. My own is because of a tumor pressing on my auditory and balance nerves. Medically it's a benign tumor but such tumors are not benign. There is, nonetheless, a very slim chance that noises in one's ear may be down to a spirit trying to communicate.
