Before sonar, there were applications where individuals actually "listened to the water" with different devices. It was largely impractical for any kind of "real science" or "real military" applications, and probably was viewed as a novelty. But the first submarines were equipped with a crude (by modern standards) sonar, so the technology developed with the military need for it.

Sonar (Sound Navigation and Ranging) is the system that uses the reflection of underwater sound waves to detect objects. This technology is commonly used in naval navigation, fishing, and underwater mapping.
One technology oceanographers use to explore the ocean floor is multibeam sonar. This advanced sonar system emits multiple sonar beams in a fan shape to create a detailed 3D map of the seafloor topography. Multibeam sonar helps scientists to accurately study the features and structures of the ocean floor.
Scientists used a combination of echo sounders, sonar, and satellites to map the ocean floor. These technologies help create detailed maps by measuring the depth of the ocean floor and identifying features such as ridges, trenches, and seamounts.
Sonar (SOund NAvigation and Ranging) is used to find objects. Sonar is used to find ships, submarines, mines, and other objects in the Navy. Sonar is used in Medicine to find unusual tumors, organs, and cells. Sonar is used in Geology to find minerals, oil, rock formationsn, and water .
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.

Most people do not hear the sonar signals used by animals, such as bats or dolphins.

SONAR (Sound Navigation and Ranging) primarily uses sonar systems that include transducers, which emit sound waves and receive echoes. These systems can be categorized into active and passive sonar. Active sonar sends out sound pulses and listens for their return, while passive sonar detects sounds made by objects in the water without emitting sound waves. Common tools used in sonar applications include echo sounders, hydrophones, and sonar arrays.
