'Sound' in the Bible

And the seven angels who had the seven trumpets prepared themselves that they might sound with their trumpets.

And I saw, and I heard an eagle flying in mid-heaven, saying with a loud voice, Woe, woe, woe, to them that dwell upon the earth, for the remaining voices of the trumpet of the three angels who are about to sound.

and they had breastplates as breastplates of iron, and the sound of their wings was as the sound of chariots of many horses running to war;

but in the days of the voice of the seventh angel, when he is about to sound the trumpet, the mystery of God also shall be completed, as he has made known the glad tidings to his own bondmen the prophets.
