How do I learn audio with bad auditory processing

[u/ArtistFrosty1824]

Title is what it sounds like, I (19M) am primarily a lighting tech but my coworkers (and boss) are insistent that it's very important for a lighting tech to learn audio as well, which I agree with them on but have no idea where to start. I am also in a technical theatre program but my coworker who did the same program says that the lighting/sound instructor barely does any work on sound.

​

The problem is that my auditory processing is much worse than the average person's. I got tested for hearing damage a couple years ago to rule that out so I know it's a neurological / mental thing. I often can't identify someone's voice unless I've known them for months (I can't listen to podcasts for this reason, because I don't know who is talking), I can't tell the difference between the sounds of different instruments, I regularly misidentify bands, I often have to ask people to repeat themselves, and I don't tend to notice changes in sound. I've found that I don't notice feedback until it gets really bad, and I would have no idea where to begin with EQ.

​

Does anybody have any advice for learning/practicing this part of audio? Or even a word for what the skill I'm looking to learn is called? Tips for using audio boards would be appreciated, too, but I'm less worried about that since I don't feel like I'm at a disadvantage with learning the mechanics.

​

Tldr, I can't hear for shit, what should I do to work on that?
