Honest question not rhetorical or sarcastic.

I never thought the helmets were all that great for hearing protection, when I was in the Navy, so I always used the foam earplugs, too.
Pressurization isn't a problem at 150 feet. I lost pressurization a couple of times at 25K+ feet (pretty rapid, but not explosive), and didn't have any problems with my ears.
We had plane lose a canopy during a PMCF flight, once. I think they were in the upper teens, or lower 20's when it happened. They brought it back for a normal landing (I was sitting at the hold short line), but they said they couldn't hear shit on the radios, because of the wind noise.
