17Fear, and the pit, and the snare, are upon thee, O inhabitant of the earth.

 18And it shall come to pass, that he who fleeth from the noise of the fear shall fall into the pit; and he that cometh up out of the midst of the pit shall be taken in the snare: for the windows from on high are open, and the foundations of the earth do shake.

 19The earth is utterly broken down, the earth is clean dissolved, the earth is moved exceedingly.

 20The earth shall reel to and fro like a drunkard, and shall be removed like a cottage; and the transgression thereof shall be heavy upon it; and it shall fall, and not rise again.

 21And it shall come to pass in that day, that the LORD shall punish the host of the high ones that are on high, and the kings of the earth upon the earth.

The sounds are a warning the Earth is about to reel to and fro like a drunkard the windows on high are open sky quakes preceding the great earthquake of the sixth seal judgement!
