Actually, I recall a study showing that most hearing damage is caused by decibel levels, not volume levels. Did you know that an infant's cry has a higher decibel level than a jet airplane engine? Certainly volume can be harmful to the ears, but in almost all cases it is the result of prolonged exposure to elevated volume levels, (such as at construction sites), over years that cause the damage.
While I do not encourage the average person to listen to headphones at maximum volume all the time, even then it is at a low enough level that hearing isn't really effected. I have to listen to my books at max volume when I am mowing the lawn if I want to hear anything over my gasoline push mower, but after 20 or so years, I can still hear someone whispering about me two rooms away, even while I am wearing my sony mdr-v150 headphones, (though without the book or music playing, obviously).
