Around the world , people know that the letters ? SOS ? are a call for help . But why is this code universal ? We know that it was designed to be short and easy to send , which is vital when an situation occurs . However , that doesn't explain why people in every country use it . In order to fully the story behind SOS , we need to go back to the early 1900s .
At that time , wireless communication was becoming common on ships , and Morse code had become well throughout the US and Europe . However , there was no standard , so there were many sets of abbreviations being used in different countries . For example , British radio telegraph operators used ? CQD ? for distress calls , because ? CQ ? addressed all stations and ? D ? for ? distress . ? Thus , CQD was understood to mean , ? All stations , distress ! ? In 1905 , Germany adopted ? SOS . ? The next year , at a convention to discuss radio issues in Berlin , delegates making the SOS signal universal . It soon spread through Europe , but wasn't officially adopted by the US until 1912 , after the sinking of the Titanic .

A typical is that SOS stands for ? Save Our Ship ? or ? Save Our Souls , ? but neither is correct . In fact , SOS was chosen because those letters were not an acronym and didn't stand for anything . It was important that the signal be from any other so that it would be easy to recognize . It's also to send in Morse code , and it looks the same upside - down or in reverse .
Though voice radio has replaced Morse code , SOS can still be used to call for help . Rescue workers still understand that with any signal , ? three short , three long , three short ? means ? Help ! ? If you need assistance at night , you can rescuers like this with a flashlight . During the day , you can use a mirror to reflect the sun's rays , or use blasts on a to send an audible call . If you enjoy hiking , camping , boating , or other outdoor activities , it could be crucial to know how to call for help in emergencies .
