Thanks. So what OscarCunningham said in sibling comment: Ambient and unwanted noise might be at 90dB. You need at least 20dB of headroom to get a good sound and range, so the PA might be (for an arbitrary attendee) at 110dB. Then I use my fancy flat-curve earplugs to chop 20dB off of everything, resulting in 90dB music and 70dB (and still drowned-out) unwanted noises. My numbers might not be right, but general idea, right?

Absolutely. But even the flattest earplugs aren't flat because not all the sound goes through the canal they plug up. Bass conducts through your whole body so you end up with 110dB of bass, 90dB mids/highs, 70dB noise. The unattenuated bass isn't damaging your ears, but it makes a non-flat experience. This is why I recommended some -12dB earplugs in another comment.
