Voice Tube
A voice tube is a communication device used on ships to transmit and receive messages between different parts of the vessel. It consists of a tube with a mouthpiece at one end and a receiver at the other end. The mouthpiece is used to speak into the tube, and the sound waves travel through the tube to the receiver, where they are heard by the person on the other end. Voice tubes are commonly used in areas of the ship where electronic communication is not possible or practical, such as in engine rooms or other noisy areas. They are also used as a backup communication system in case of power failure or other emergencies.
