Temporary to permanent hearing loss

Good day all
I’ve just found out that I have hearing loss and am new to this forum so please forgive me if this is not the correct place to ask this.

In the past I have had temporary hearing loss that went to the point of requiring hearing aids but in time improved to the point that aids were no longer required. I am 49 now and just recently tested for hearing loss and it is time for hearing aids. My hearing has slowly diminished since the time that the temporary hearing loss improved and since has diminished.

Does anyone know any articles or studies that are on temporary hearing loss improving than slowing diminishing to the point that it becomes permanent hearing loss?

Thanks
