I'm not sure. I sometimes get tinnitus, but despite being told by that not-very-well-informed hearing therapist that tinnitus is either caused by deafness or it's psychological, mine is a vascular form called pulsatile tinnitus, which was triggered by flu and tends to re-emerge when I have a cold. Those white noise generators are actually aimed at people with tinnitus, if it's any help, and they did help mine a certain amount. What sort of tinnitus do you have? I think tinnitus is far better-recognised than APD, so you'd be better finding somewhere that specialises in APD and asking them if they know of a connection to tinnitus, rather than going to a random tinnitus clinic and finding out whether they've even heard of APD. The verbal paraphasia thing - me too! Much worse at certain levels of gabapentin, and oddly, it seemed to improve when I went up to the higher doses, only to come back now that we have me down to a medium dose again. Well, either it's that or a hormonal thing, I'm having bad PMS this month. When I'm typing, I'm more likely to do things like substitute a different form of the same word, such as an adverb for an adjective, and usually a longer form. Plus my ability to spell has worsened, of course.
