Study Notes
Echolocation: Biological and Technological Process
- Echolocation is a process that involves emitting sound waves and listening to the echoes to determine location, distance, and shape of objects in the environment.
Biological Echolocation
- Documented in animals for centuries, with ancient Greeks observing bats using echolocation to navigate and find food in the dark.
- Scientific study of biological echolocation began in the early 20th century with the work of British naturalist Donald Griffin.
- Griffin's research showed that bats use echolocation to navigate and hunt.
- Found in various animals such as bats, dolphins, and some species of whales.
- Relies on the emission of sound waves, usually in the form of clicks or vocalizations.
- Animals emit sound waves and listen for echoes produced when sound waves bounce off objects in their environment.
- By analyzing echoes, animals can determine the location, distance, and even shape of objects around them.
Technological Echolocation
- Originated in the early days of submarine warfare during World War I.
- The British navy developed a primitive form of sonar (known as "ASDIC") to detect submarines.
