Generally, I suspect that there's a link between the neural structure of the brain and the auditory system of that under specific conditions results in tinnitus (for preemie and non-preemie people). In preemies the neural structure is different, so there might be a difference in auditory attention (very sensitive auditory system) and attention in general. So they might have a harder time with habituation of hyperacusis, tinnitus or hearing loss.
