So it looks like noise/acoustic trauma tinnitus can resolve spontaneously, by itself. If there were people who got tinnitus after their eardrums were ruptured by an explosion, who got better, surely there is a chance that we can get better...

In that dissertation, the author writes (on page 35 of 77):
"Of conscripts exposed to a single shot, tinnitus was initially present in 96% and hearing
loss in 52% (I). At discharge, 23% had tinnitus, 23% had hearing loss, and 39% had
either symptom still at discharge from the military service, indicating a long-lasting
effect after exposure to only a single shot. {Note: The figures above and the law for unions and intersections from probability theory imply that 7% had both tinnitus and hearing loss. This means that 70% out of 96%, or almost 73% had recovered from tinnitus.}
Although tinnitus was present in 97% of conscripts after AAT, the majority had resolved
by the end of the military service, at which time tinnitus was still present in 32%, and
68% had resolved. Hearing loss was present in 48% after AAT and 23% persisted at the
end of service. Thus, at the last visit before discharge, tinnitus, hearing loss or both were
present in 45%, and 55% were cured. Most of the conscripts received hyperbaric oxygen
treatment, so it is not known, what the spontaneous recovery rate of symptoms was, and
how many were cured due to treatment."

Page 15:
"In a study of a terrorist bomb explosion in a municipal bus, where 22 people lost their lives and 48 were wounded, 23 patients were hospitalized, and 17 of them were followed for six months in the otolaryngologic outpatient clinic (Cohen et al., 2002). All but one patient had a perforated TM. The most common auditory complaints of these 17 patients were aural fullness and pressure (88%), tinnitus (88%), otalgia (53%), dizziness (41%) and aural discharge (53%). After the six month follow-up period, 40% of the patients initially complaining of tinnitus still had tinnitus. Tinnitus had improved in 13%, and in 47% it had disappeared by the end of the six month follow-up period."
and, on the same page:
"In that study, the patients underwent initial examination from the first day up to 10 months after the explosion, so the frequency of acute effects is not known. Pahor found the most frequent otologic symptoms in 111 hospitalized bombing victims to be deafness, high-pitched tinnitus, TM perforations, and earache. Otologic problems were found in less than one-third of the patients. Deafness was reported in 27 cases, and tinnitus in 26 cases. Twenty patients had perforated TMs. Hearing loss was mostly in the high-tones. In that study, all but one tinnitus case resolved spontaneously under follow-up (Pahor, 1981)."
So it looks like noise/acoustic trauma tinnitus can resolve spontaneously, by itself. If there were people who got tinnitus after their eardrums were ruptured by an explosion, who got better, surely there is a chance that we can get better...
