A number of researchers, including the French physicist Paul Langevin, had worked out the theoretical principles for sonar, but getting a detection device to actually work on a warship proved daunting.Working closely with Langevin, Boyle and his group managed to produce working ultrasonic quartz transducers by 1917."It stands out as the most important new piece of military equipment developed by any Canadian scientist during the First World War." Boyle was not to be seduced by a career in the military, however.He turned down an offer from the British Admiralty to work for twice his U of A salary and ended up back at the university, where two years later he became dean of the newly established Faculty of Applied Science".This body was formed during the war of 1914-1918, and organized much research and experimentation for the detection of submarines, however, no committee bearing this name has been found in the Admiralty archives." This newspaper article titled "Inventor of Sonar Ignored By History" was written by Geoff Mc Master of the Express News Staff and gives some insight about the invention of ASDIC/SONAR.

During the later part of World War I, submarine locators were developed.In the RCN, the term SONAR started coming into general useage around 1955 and in the Royal Navy, around 1964.
