The 'Silence in Heaven' text comes about after the events of the sixth seals and before the seventh seal of Revelation:
Revelation 8:1 King James Version (KJV)
8 And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.
We also find at the seventh vial that a voice is heard saying 'It is done'..:
Revelation 16:15-17 King James Version (KJV)
15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
16 And he gathered them together into a place called in the Hebrew tongue Armageddon.
17 And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.
And we find another instance of prophetic time for a short space, in the use of a hour, for the destruction of Mystery Babylon
Revelation 18:16-18 King James Version (KJV)
16 And saying, Alas, alas that great city, that was clothed in fine linen, and purple, and scarlet, and decked with gold, and precious stones, and pearls!
17 For in one hour so great riches is come to nought. And every shipmaster, and all the company in ships, and sailors, and as many as trade by sea, stood afar off,
18 And cried when they saw the smoke of her burning, saying, What city is like unto this great city!
How do they relate to one another...
