As soon as the ark of the covenant of the LORD came into the camp, all Israel gave a mighty shout [teruah], so that the earth resounded. 1 Samuel 4:5

And the LORD spoke to Moses, saying, “Speak to the people of Israel, saying, In the seventh month, on the first day of the month, you shall observe a day of solemn rest [special Sabbath], a memorial teruah [same Hebrew word as "shout" in Joshua 6 about the fall of Jericho's city walls, but also used for other joyful noises such as clapping, cymbals, etc.], a holy convocation. You shall not do any ordinary work, and you shall present a food offering to the LORD.” Leviticus 23:23-25

(Note: The Hebrew word "trumpet" or "shofar" (ram's horn) is not present in the above passage, whereas it is in the one below. That is not to say there is no trumpet or shofar implied, but that the word is not limited to that method of making sound.)

On the morning of the third day there were thunders and lightnings and a thick cloud on the mountain and a very loud trumpet [shofar] blast, so that all the people in the camp trembled. Then Moses brought the people out of the camp to meet God, and they took their stand at the foot of the mountain. Now Mount Sinai was wrapped in smoke because the LORD had descended on it in fire. The smoke of it went up like the smoke of a kiln, and the whole mountain trembled greatly. And as the sound of the trumpet [shofar] grew louder and louder, Moses spoke, and God answered him in thunder. The LORD came down on Mount Sinai, to the top of the mountain. And the LORD called Moses to the top of the mountain, and Moses went up. Exodus 19:16-20

Then I saw another mighty angel coming down from heaven, wrapped in a cloud, with a rainbow over his head, and his face was like the sun, and his legs like pillars of fire. He had a little scroll open in his hand. And he set his right foot on the sea, and his left foot on the land, and called out with a loud voice, like a lion roaring. When he called out, the seven thunders sounded. And when the seven thunders had sounded, I was about to write, but I heard a voice from heaven saying, “Seal up what the seven thunders have said, and do not write it down.” And the angel whom I saw standing on the sea and on the land raised his right hand to heaven and swore by him who lives forever and ever, who created heaven and what is in it, the earth and what is in it, and the sea and what is in it, that there would be no more delay, but that in the days of the trumpet call to be sounded by the seventh angel, the mystery of God would be fulfilled, just as he announced to his servants the prophets. Revelation 10:1-7

Then the seventh angel blew his trumpet, and there were loud voices in heaven, saying, “The kingdom of the world has become the kingdom of our Lord and of his Christ, and he shall reign forever and ever.” And the twenty-four elders who sit on their thrones before God fell on their faces and worshiped God, saying, “We give thanks to you, Lord God Almighty, who is and who was, for you have taken your great power and begun to reign. The nations raged, but your wrath came, and the time for the dead to be judged, and for rewarding your servants, the prophets and saints, and those who fear your name, both small and great, and for destroying the destroyers of the earth.” Then God’s temple in heaven was opened, and the ark of his covenant was seen within his temple. There were flashes of lightning, rumblings, peals of thunder, an earthquake, and heavy hail. Revelation 11:15-19
