'Sound' in the Bible

Then you are to sound a trumpet loudly in the seventh month, on the tenth day of the month; you will sound it throughout your land on the Day of Atonement.

“I will put anxiety in the hearts of those of you who survive in the lands of their enemies. The sound of a wind-driven leaf will put them to flight, and they will flee as one flees from a sword, and fall though no one is pursuing them.
