I would worry about saving your butt and then deal with any hearing issues. This is a non-issue...nothing you should concern yourself about in the least. Nothing you can do about it either unless you want to call time-out to put hearing protection on prior to defending yourself.
You'll be fine from some exposure(from a once in a lifetime SD shooting)...it's the constant battering that will damage your ears should you never wear protection at the range.
