I'm on the run so can't respond in depth, but check out ototoxic drugs which attack the auditory nerve. SSRIs may not be directly ototoxic but numerous studies have shown that sertraline can cause tinnitus, due to the role that serotonin plays in filtering audio signals. So there are multiple causes of tinnitus, and the impact of SSRIs is partially known but not fully understood.
