'Sound' in the Bible

You shall then sound a ram’s horn abroad on the tenth day of the seventh month; on the day of atonement you shall sound a horn all through your land.

As for those of you who may be left, I will also bring weakness into their hearts in the lands of their enemies. And the sound of a driven leaf will chase them, and even when no one is pursuing they will flee as though from the sword, and they will fall.
