'Sound' in the Bible

Even lifeless things giving a sound, whether pipe or harp, if they give not distinction to the sounds, how shall it be known what is piped or harped?

For also, if the trumpet give an uncertain sound, who shall prepare himself for war?

There are, it may be, so many kinds of voices in the world, and none of undistinguishable sound.

If therefore I do not know the power of the sound, I shall be to him that speaks a barbarian, and he that speaks a barbarian for me.

in an instant, in the twinkling of an eye, at the last trumpet; for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
