"...is that the skin in the ears isn't really tough enough to stick something in there for too long…" I use earplugs every night. The ones I think are most comfortable block up to 38 db at low frequencies and 48 db for high frequencies. They are really soft - and I mean: really. I sleep like a baby (and I don't miss my alarm in the morning). Still, in case of fire during a REM phase, I probably will die ;o). I also have professional plugs from the acoustician that were fitted to my ears, but they are much harder (silicone). Those I can wear during the day (underground, bus etc.) but not during the night. They do hurt the ears brutally. The little movements that happen, when the ear rubs the pillow are sufficient to cause severe pain.
