Those who can see their environments often do not readily perceive echoes from nearby objects, due to an echo suppression phenomenon brought on by the precedence effect. However, with training, sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability. [9]
Like electric fish, echolocating animals are susceptible to jamming from other animals of the same species emitting signals in the nearby environment. [8] To avoid such jamming, bats use a strategy also employed by electric fish to avoid this jamming: a behavior known as jamming avoidance response (JAR). [8]
Unlike some human-made sonars that rely on many extremely narrow beams and many receivers to localize a target (multibeam sonar), animal echolocation has only one transmitter and two receivers (the ears) positioned slightly apart. The echoes returning to the ears arrive at different times and at different intensities, depending on the position ...
