No, sonar is not known to be harmful to humans even with prolonged exposure.
The word "sonar" comes from a combination of "sound" and "navigate" or "ranging." It is an acronym for Sound Navigation And Ranging. Sonar is a technology that uses sound waves to detect objects underwater.
Sonar uses sound waves to detect objects underwater by bouncing off them and measuring the time it takes for the waves to return. The distance to an object is then calculated based on the time it takes for the sound waves to travel to the object and back to the sonar device. This process allows sonar to estimate the range to objects in the water.
Sonar works by emitting sound waves into the water that bounce off objects and reflect back to the sonar device. By measuring the time it takes for the sound waves to return, sonar can determine the distance to the objects and create a picture of the underwater environment.
Sonar was used widely in World War II in an effort to locate enemy submarines. It wasn't as sophisticated as it is today, but it did help. Actual numbers are difficult to come by, but sonar was effective in the successful attacks on several submarines.
