The natural function of the cilia in the lungs is to remove irritants and particles from the lungs, but there is a point in which the chemicals/particles inhaled can cause damage. High intensity noise damaging your ears is definitely comparable to lungs damaged by something like smoking, working in dusty working conditions, or being exposed to irritants/carcinogens. Once you get COPD or emphysema there is no looking back, just like the folks with tinnitus. The cilia in particular are much different physiologically speaking, but the long term damage is similar. Unfortunately something like tinnitus not attributed to loud noise is uncommon to the point where I think even doctors just have to take an educated guess. It is possible that your condition may be reversible in the future if the cilia in your ear arent damaged, but there can be other issues with the nerves that are beyond repair as well. As far as I know there is no cure, but I have read that spikes can last months before going down so there is hope perhaps.
