Proclaiming loudly is a way to make a statement or announcement in a very emphatic manner. Blaring, which has five letters, is a verb meaning to make a loud, harsh sound. Trumpeting, with seven letters, is another verb meaning to make a loud, clear sound, usually with a musical instrument. Resounding, also with seven letters, is a verb meaning to echo or reverberate loudly. All three words can be used to describe the act of proclaiming something loudly.
