You see this in old movies. The captain of the ship grabs a tube, blows into it and then gives the order to the engine room to reduce speed, etc. What is the name give to the system?

A surprisingly useful means of communication is the speaking tube. The tube, perhaps 3/4" in diameter, can be led on a tortuous route, such as from the bridge to the engine room of a ship. At each end, there should be a bell-shaped termination or cone, stopped with a plug that includes a whistle like those used on teakettles. To use the tube, simply withdraw the plug and blow into the tube, which sounds the whistle at the other end. When your party answers, a conversation can be carried on as if you were face-to-face. This extremely simple and rugged device never needs batteries replaced.

The speaking tube. This was used before they had intercoms on ships and was surprisingly effective.
