invented by the U.S. Navy in 1922 and by World War II became a strategic weapon for airborne, surface ship, and underwater surveillance
When was the first sonar invented?
In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echo location to detect submarines" using the piezoelectric properties of the quartz.
Where was Albert Einstein when he invented his first invention?

When was sonar developed?
In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echo location to detect submarines" using the piezoelectric properties of the quartz. He was too late to help very much with the war effort, however, Langévin's work heavily influenced future sonar designs. The first Sonar devices were passive listening devices - no signals were sent out. By 1918, both Britain and the U.S had built active systems, in active Sonar signals are both sent out and then received back. Acoustic communication systems are Sonar devices where there is both a sound wave projector and receiver on both sides of the signal path. The invention of the acoustic transducer and efficient acoustic projectors made more advanced forms of Sonar possible.
