'Sound' in the Bible

when suddenly there came from the sky a sound as of a strong rushing blast of wind. This filled the whole house where they were sitting;

It is His name-- faith in that name being the condition--which has strengthened this man whom you behold and know; and the faith which He has given has made this man sound and strong again, as you can all see.

Meanwhile the men who travelled with Saul were standing dumb with amazement, hearing a sound, but seeing no one.

For the things you are saying sound strange to us. We should therefore like to be told exactly what they mean."
