My son cries bad when I sneeze?

Daddys away so it's usually just us and it's pretty quiet...but like he is socialized a lot and does hear noise but a few times lately when I was feeding him I sneeze and he freaks out..like he BARELY cries either this is the one where they actually go red and pout and scream LAL...Anyone else? Just a wierd reason to cry...maybe hes scared
