A note of caution regarding earplugs: they can introduce infection, which in turn (I suspect) may play a role in triggering or causing tinnitus. It probably depends on individual predisposition and climate (to me it happened in hot humid environment), but I recommend caution.

I wish I could use earplugs (or IEM headphones with good sound isolation) a lot of the time, but I found out the hard way (after infection subsided I have intermittent tinnitus as well).
