Echolocation is a skill we usually associate with animals such as bats and whales, but some blind humans also use the echoes of their own sounds to detect obstacles and their outlines. ... Despite how useful this skill can be, very few blind people are currently taught how to do it.

Who uses echolocation?
Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using reflected sound. This allows the animals to move around in pitch darkness, so they can navigate, hunt, identify friends and enemies, and avoid obstacles.
What does echolocation have to do with humans?
Human echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects, by actively creating sounds: for example, by tapping their canes, lightly stomping their foot, snapping their fingers, or making clicking noises with their mouths.
How do humans echolocate like bats?
People who use "echolocation" employ it in a very similar way to bats - producing clicks that bounce off objects and "sonify" them into a picture of the surroundings. A study of experts in the technique has revealed how louder clicks allow "echolocators" to see behind them.
How accurate is human echolocation?
They went from an average accuracy of 80 percent with angles of 135 degrees to 50 percent when the disk was directly behind them. The researchers also found that the volunteers varied both the volume and rate of clicks they made when attempting to locate something.
How important is echolocation to the life of animals to humans?
Echolocation is important to marine mammals because it allows them to navigate and feed in the dark at night and in deep or murky water where it is not easy to see. Toothed whales, including beluga whales, sperm whales, dolphins, and porpoises are known to echolocate.
What are some examples of echolocation?
Bats, for example, use echolocation to find food and avoid flying into trees in the dark. Echolocation involves making a sound and determining what objects are nearby based on its echos. Many animals use echolocation, including dolphins and whales, and humans do as well.
How does echolocation work?
Echolocation is the use of sound waves and echoes to determine where objects are in space. ... To echolocate, bats send out sound waves from the mouth or nose. When the sound waves hit an object they produce echoes. The echo bounces off the object and returns to the bats' ears.
Can you train yourself to echolocate?
With just a few weeks of training, you can learn to “see” objects in the dark using echolocation the same way dolphins and bats do. With just a few weeks of training, you can learn to "see" objects in the dark using echolocation the same way dolphins and bats do. ...
Do blind people see black?
The answer, of course, is nothing. Just as blind people do not sense the color black, we do not sense anything at all in place of our lack of sensations for magnetic fields or ultraviolet light. ... To try to understand what it might be like to be blind, think about how it “looks” behind your head.
Why are echoes useful?
An echo is the sound you hear when you make a noise and the sound wave reflects off a distant object. Besides the novelty of hearing your words repeated, echoes can be used to estimate the distance of an object, its size, shape and velocity, as well as the velocity of sound itself.
Can humans click like dolphins?
Much like dolphins or bats, a human echolocator generates sharp clicking sounds with their tongue. "They are made by pressing the tongue against the soft palate [roof of the mouth] and then quickly pulling the tongue down. ... This vacuum then 'pops', and this creates the 'click' sound," says Lore.
Can echolocation see through walls?
Visually, you can see through it, it is perfectly transparent, but for echolocation, it might as well be a solid wall. ... In a recent study, Lore found even further details about the inner workings of human echolocation. We know bats and other animals adjust the sounds they make when their environment changes.
How is echolocation pronounced?
Break 'echolocation' down into sounds: [EK] + [OH] + [LOH] + [KAY] + [SHUHN] - say it out loud and exaggerate the sounds until you can consistently produce them.
How do humans use sounds?
The simplest and most obvious use of sound energy is for hearing. Humans can hear frequencies between about 20 Hz and 20,000 Hz. ... Another way that we use sound waves to learn about our surroundings is SONAR (short for Sound Navigation And Ranging), which is used to map objects on the ocean floor.
How far can people echolocate?
We found that experienced echolocators can detect changes in distance of 3 cm at a reference distance of 50 cm, and a change of 7 cm at a reference distance of 150 cm, regardless of object size (i.e. 28.5 cm vs. 80 cm diameter disk).
