What does "blatant" mean?

Blatant: Bellowing, as a calf; bawling; brawling; clamoring; disagreeably clamorous; sounding loudly and harshly. "Harsh and blatant tone." R. H. Dana. A monster, which the blatant beast men call. Spenser. Glory, that blatant word, which haunts some military minds like the bray of the trumpet. W. Irving.
