What communication method can be used to contact the outside world after diving into the deep sea? It is underwater acoustic detection. Diving into the deep sea is a very challenging adventure. It requires facing huge water pressure and unknown dangers. Traditional communication equipment cannot function in the depths of the sea, so divers usually use sonar and satellite communications equipment to communicate with the outside world.
Answer: Hydroacoustic Detection
In the deep sea, radio signals will be affected by water quality, ocean currents, etc., and the efficiency of wireless communication will become very low. Hydroacoustic detection can support machines such as deep-sea detectors to communicate with humans. The principle of underwater acoustic detection is to convert acoustic energy and electrical energy into each other, and then use technology to perform signal processing to achieve communication.
