'Sound' in the Bible

It happened on the third day, when it was morning, that there were thunders and lightnings, and a thick cloud on the mountain, and the sound of an exceedingly loud trumpet; and all the people who were in the camp trembled.

When the sound of the trumpet grew louder and louder, Moses spoke, and God answered him by a voice.

All the people perceived the thunderings, the lightnings, the sound of the trumpet, and the mountain smoking. When the people saw it, they trembled, and stayed at a distance.

It shall be on Aaron to minister: and its sound shall be heard when he goes in to the holy place before Yahweh, and when he comes out, that he not die.
