If you have two and half hours to kill, I recommend this talk. There are a few speakers, and each of them focus on different areas of listening. General theme is headphone listening, but the talks range across a few topics.
Main thing I liked is the set of diagrams below. Clearest demonstration I've seen of age-related or noise-induced hearing loss.
Here are normal equal loudness curves for free field listening:
Here's a simulated 50dB hearing loss audiogram:
And here are the resulting equal loudness contours:
So hearing loss is not fixable by EQ. Don't pick, or suggest to others, speakers or headphones with boosts as a way of compensating for loss. Strange how often you see that piece of (wrong) advice.
Edit: The equal loudness contours for people with hearing loss show compression. You are still capable of perceiving different loudness levels, and the range of very quiet to very loud exists for you—it's just mapped across a reduced physical SPL range.
