The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...

Animal echolocation, non-human animals emitting sound waves and listening to the echo in order to locate objects or navigate. Human echolocation , the use of sound by people to navigate. Sonar ( so und n avigation a nd r anging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines.
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...

Several explanations for why cetaceans strand themselves have been proposed, including changes in water temperatures, [3] peculiarities of whales' echolocation in certain surroundings, [4] and geomagnetic disturbances, [5] but none have so far been universally accepted as a definitive reason for the behavior.
[3] [4] [5] Only in the 1940s did a series of experiments performed in the Cornell Psychological Laboratory show that sound and hearing, rather than pressure changes on the skin, were the mechanisms driving this ability. [1] The field of human and animal echolocation was surveyed in book form as early as 1959 [6] (see also White, et al. (1970 ...
Smaller animals like insects use different techniques as the separation of the ears are too small. [27] For the process of animals emitting sound to improve localization, a biological form of active sonar , see animal echolocation .
