But that's the thing, I'm in the similar position to others in the chain - last week, an audiologist said my hearing was tremendously good. But if there's noise around me, I cannot process what people are saying.

I'm not sure what you mean by "only if you've learned some helplessness." I'm not a complete idiot, I can generally guess what someone is saying based on context, but if I'm having a conversation with Group A in a loud environment, and someone from group B turns to me and says something, I don't have much context as to what they're saying.

(Also, a PSA: if someone who didn't hear you says, "what", or "can you say that again?", don't just repeat the last three words you said. Please repeat the entire sentence. I know that usually, the last few words provide enough context to reconstruct the sentence, but if you just tell me "this Sunday?" it's usually not enough, you have to just say, "Are you still planning on reconfiguring the encambulator this Sunday?")
