   Animals and Echolocation

While it is apparent that most animals are able to produce sounds of their own, the reasons behind animal sounds are not often known. It is assumed that, like humans, animals produce sounds for a variety of reasons. In general, it is thought that animals communicate much like the way humans talk, though in a more primitive sense. Some animals, however, seem to have advanced aural abilities, some that even humans lack, one of whichis what we refer to today as echolocation.

Echolocation, also known as biosonar / be known for something / be know as being something / be known to a group of people , is the way an animal uses sounds and their echoes to examine their surrounding environment and objects in it. Using echolocation, an animal can hunt for food, avoid danger, or virtually any task that humans use sight to accomplish. In many ways, echolocation operates similarly to a boat's or submarine's sonar, and this relationship was actually one of the major reasons for the initial discovery of echolocationby whom?. In World War II, a major development was that of sonar for detecting submarines. The devices used to pick up those sounds, called hydrophones, also picked up many sounds from sources that were found to be whales or dolphins.

讀著蔣勳的書。精緻的深藍色書皮上襯著不經意留下的水漬與磨損的刻痕,就如同生活中那些大大小小的不如意,遠看仍是美。
