An earful is a long, angry talk someone gives you because they are unhappy with what you did. You get an earful, or someone gives you an earful; you do not “do an earful”. It is informal, common in both British and American English, and a bit softer-sounding than a full shouting match, though it can still sting. Parents, partners, and bosses give earfuls. Though actually, the -ful here does not mean “full of ears”; it means “as much angry talk as an ear can take”. It is always about words of complaint in this sense, never about how loud a speaker or a concert is (that is closer to ear-splitting).
