Advantages and Disadvantages of SONAR Technology
The Negative Effects of SONAR
The world was first introduced to SONAR during World War II. It was originally created by the Navy, for military use. It has since been used for a number of other things. Many people argue the need for the use of his device because of its powerful effects. Even though sonar can be used for positive medicinal purposes and research applications, SONAR technology can have harmful effects on marine life, humans, and unborn children.
To begin, SONAR has been used throughout history for several different applications. The uses of SOONAR began with the Navy. The Navy believed that
SONAR was the only efficient way to track hidden enemy submarines [Alexander]. The
Navy has also used SONAR to teach inexperienced sailors how to detect problems in their surroundings. Other uses of SONAR besides military uses now include commercial and scientific uses.
The word SONAR was invented by F.V. Ted Hunt who was the director of the
Harvard Underwood Sound Laboratory. The word SONAR was developed from the words “sound navigation and ranging” [ScienceMag]. There are two major types of
SONAR, passive and active. Passive sonar acquires sound waves reflected by another source, but it does not give off any noise. Passive SONAR has proved not to be as reliable as active sonar. The other type of SONAR is active SONAR. Active
SONAR uses an apparatus called a transmitter which changes electrical energy to sound energy to transmit sound waves. These sound waves create anthropogenic noises, which imitate the sounds of marine mammals [Mora]. These sound waves go through the water until they hit an object. The sound waves then return to the receiver
on the sonar computer. After the computer receives the waves, it changes them back into electrical signals, which then produce a picture. Active SONAR is able to penetrate water and create images of what would otherwise be considered invisible because of its extreme depths.
