There are two aspects to diver communications: Divers who are diving together as a team need to communicate for safety and efficient completion of the task, and divers who are diving with a surface support team need to communicate with the surface team, also for safety and efficiency.

More recently, through-water systems have been developed which do not use wires to transmit the signal. These allow communications over limited distances between divers and with the surface, using a push to talk system, which minimises power consumption by transmitting only on demand.there is a built in speaker behind the perforations on the panel.Both hard-wired (cable) and through-water electronic voice communications systems may be used with surface supplied diving.This system was well-established by the mid-20th century, and has been technologically improved, but is still in common use for surface-supplied divers using lightweight demand helmets and full-face masks.The condition of the diver can be monitored by the surface support team by listening to the continuous transmission of sound from the diver, which allows the supervisor to monitor the diver's breathing pattern.In the early 20th century electrical telephone systems were developed which improved the quality of voice communication.

These used wires incorporated into the lifeline or air line, and used either headsets worn inside the helmet or speakers mounted inside the helmet.

This is considered important both for managing the diving work, and as a safety measure for monitoring the condition of the diver.

The traditional method of communication was by line signals, but this has been superseded by voice communication, and line signals are now used in emergencies when voice communications have failed.

These include sound-based systems, visual systems and tactile systems.

A small number were made by Seibe-Gorman, but the telephone system was introduced soon after this and since it worked better and was safer, the speaking tube was soon obsolete, and most helmets which had them were returned to the factory and converted.

Wired systems are more popular as there is a physical connection to the diver for gas supply in any case, and adding a cable does not make the system any different to handle.
