Hearing protection is mandatory in the workshop where I work. Somehow I managed to start wearing earplugs most of the time while I drive, and more recently have been leaving them in when I go to the supermarket and when I get home. I'll occasionally sleep with them in too. It certainly does make a difference, in my experience.
