'Sound' in the Bible

And the seven angels that had the seven trumpets prepared themselves to sound.

And I saw, and I heard an eagle, flying in mid heaven, saying with a great voice, Woe, woe, woe, for them that dwell on the earth, by reason of the other voices of the trumpet of the three angels, who are yet to sound.

And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots, of many horses rushing to war.

but in the days of the voice of the seventh angel, when he is about to sound, then is finished they mystery of God, according to the good tidings which he declared to his servants the prophets.
