ACOUSTIC LOCATION Meaning and
Definition
-
Acoustic location refers to a method of determining the position or location of a sound source using the properties of sound waves. It involves the use of specialized equipment to detect and analyze sound signals in order to determine the direction and distance of the source.
This technique relies on the principle of triangulation, where multiple sensors or receivers are strategically placed at known locations. These sensors capture the sound wave arriving at slightly different times due to the distance between them and the sound source. By analyzing the time differences in the received signals, the exact location of the source can be calculated.
Acoustic location systems were widely used during World War I and World War II for artillery detection, ranging, and locating enemy aircraft and submarines. The technology has evolved over time, with advancements in signal processing and sensor design.
Modern applications of acoustic location include wildlife monitoring, environmental research, and navigation systems. It is also used in various industries for noise control and sound detection in manufacturing processes.
Acoustic location has several advantages, such as its ability to operate in any weather conditions and its relative simplicity compared to other location methods. However, it also has limitations, such as reduced accuracy in complex environments with multiple sound reflections and obstructions. Nonetheless, acoustic location continues to be an essential tool in many fields where precise sound source localization is required.
Etymology of ACOUSTIC LOCATION
The term "acoustic location" derives from the combination of two root words: "acoustic" and "location".
The word "acoustic" relates to the sense of hearing or sound. It originates from the Greek word "akoustikos", which means "pertaining to hearing". The Greek word is derived from the verb "akouo", which means "I hear" or "I listen".
The word "location" refers to a particular place or position. It comes from the Latin word "locare", which means "to place" or "to put". The Latin word is a combination of "loco" meaning "place" and the suffix "-ation" denoting action or process.
Therefore, when combined, "acoustic location" refers to the process or method of locating or determining the position of an object or sound source using sound or the sense of hearing.
