'Sound' in the Bible

And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?

For if the trumpet give an uncertain sound, who shall prepare himself to the battle?

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 a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
