Question: 1 / 400

What is the purpose of a sound-powered phone circuitry in a ship?

To control the ship's steering

To access communication systems without power

The purpose of sound-powered phone circuitry on a ship is to facilitate communication systems without requiring an external power source. This unique communication method leverages the principle of converting sound energy into electrical energy, allowing personnel to communicate even in circumstances where conventional electrical systems may fail, such as during power outages or emergencies. Sound-powered phones rely solely on the voice sounds produced by users, which are transmitted through the circuitry. As a result, they serve a crucial role in maintaining communication capabilities in critical situations, ensuring that crew members can effectively coordinate operations and respond to emergencies.

The other options focus on specific functions (like navigation and monitoring systems) that require powered electronic systems, which do not align with the inherent benefits of sound-powered communication technology.
