What is an acoustic mine?

Acoustic mine is a type of sea mine that responds to pressure changes and acoustic information that explodes when a ship of a certain size goes through it. The acoustic mines were historically laid in the controversial sea tires during the war; Modern mines are in fact quite sophisticated and many of them are capable of programming to avoid, for example, a threat to friendly traffic. Acoustic mines are among the large family of tools used to obtain and hold the maritime territory during the war. Because the acoustic mine is a military tool, the ownership of such facilities is usually limited to military or research organizations.

Early acoustic mines, such as those used in World War II, simply used directional sensors that passively listened to the sounds of passing boats and submarines. Modern acoustic mines are usually capable of passive and active modes, similar to sonar systems on ships. Passive listening modes in the acoustic mine CBIat sensitizoChristmas on the sound of specific engines or other characteristic acoustic signatures, while active modes can broadcast acoustic pulses to seek and identify goals.

In addition to response to acoustic information, many acoustic mines are also programmed to respond to pressure changes. When ships and submarines travel, they push out large amounts of water, causing changes in pressure that can be read by sensitized monitors in the acoustic mine. Many acoustic mines are able to distinguish between large and small ships, allowing them to target larger military ships without damaging fishing ships and other smaller vessels.

There are several ways to deploy an acoustic mine. Classically, militation used freely floating mines, which can cause problems when driving outside the sea slices in which they are deployed. Others tied their mines with anchors to remain a specific place and in a particular hlibce. It is also possible to distract sea mines along the ocean bottom; This technique is often used to use submarines that tend to embrace the ocean bottom on enemy territory.

, along with other types of mines, acoustic mines were the topic of some claim. Thousands of injuries cause worldwide mining annually because the mines are unable to distinguish between innocent and potentially threatening operations. Anti -anti -organizations tried to persuade global militants to leave mining practice or use mines that are easier to deactivate; For example, some acoustic mines can be equipped with computer systems that respond to a coded pulse that can be used to deactivate down.
