ACOUSTIC SONAR Meaning and
Definition
-
Acoustic sonar refers to a system utilized for underwater navigation and detecting objects by transmitting, receiving, and interpreting sound waves. The term "acoustic" pertains to sound, while "sonar" stands for sound navigation and ranging. This technology is primarily employed in marine applications to aid in several operations, including mapping the ocean floor, detecting underwater hazards or obstructions, locating underwater objects, and facilitating underwater communication.
An acoustic sonar system typically consists of at least one transducer that emits sound waves into the water. These sound waves travel through the medium, and upon encountering an object or reflecting off the bottom surface, they bounce back as echoes. The echoes are then captured by the same or a different transducer, which converts them into electrical signals. These signals are subsequently processed to determine the distance, depth, and location of the obstacles or objects.
Acoustic sonar relies on the principles of sound propagation, echo reception, and signal analysis to create an accurate representation of the underwater environment. Its application in various sectors, such as hydrographic surveys, maritime defense, fisheries, and offshore industries, has proven valuable in ensuring safe and efficient operations.
By employing acoustic sonar technology, researchers and professionals can gain a better understanding of the underwater realm, assisting in the exploration, management, and preservation of marine ecosystems.

Etymology of ACOUSTIC SONAR
The word "acoustic sonar" is a combination of two terms: "acoustic" and "sonar".
The term "acoustic" derives from the Greek word "akoustikos", which means "pertaining to hearing". It entered the English language in the early 18th century, referring to the branch of physics that studies sound and its transmission.
"Sonar" is an acronym for "SOund Navigation And Ranging". It was developed during World War II and refers to the use of sound waves to detect and locate underwater objects, as well as to measure water depth. The term "sonar" was coined in the United States Navy in 1942.
"Acoustic sonar" thus combines these two terms to describe a type of sonar that uses sound waves for detecting and locating objects underwater.
