The ability to “see” with sound is an intriguing concept. Sound waves scattered from an object can carry much the same image information concerning the object as do scattered light waves. Man is not naturally equipped to efficiently data-process this kind of information. He cannot obtain a good mental image of an object simply by listening to scattered sound. However, nature has provided many examples of animals that can do this. Only recently has this fact been fully appreciated. In 1793, the Italian scientist Spallanzani concluded that bats must have some “new sense” that humans are not aware of. It was not until 1920 that the principle of operation of the “new sense” was found to be somewhat similar to that used by the sonar systems developed a few years before, during World War I. By now it is well known that several cetaceans, such as the dolphin, also have excellent capability for navigating and locating food by means of sonic energy. |
