Watch this blind male ‘see’ a universe with sound
A singular skill
Most blind people conduct with beam dogs and canes, though a few have grown what seems to be a kind of superpower: they can echolocate. Like bats or dolphins, these people have schooled to beget sound, and listen to reflections and echoes of these sounds to asian themselves and locate objects in their environment.
Brian Borowski, a mechanism programmer in London, Ont., was innate blind. As a child, he schooled that short, pointy clicks of his tongue opposite a roof of his mouth could be used as a sonar source. Indoors, he listens for how these clicks rebound off walls, windows and doors to navigate around buildings, and he can locate objects as tiny as 10 or 20 centimetres. Outdoors, he echolocates buildings, fences, trees, flare posts and cars, and navigates what he calls his three-dimensional universe of sound.
Understanding tellurian echolocation
Dr. Lore Thaler has been study tellurian echolocation for some-more than a decade.  In fact, some of her early work in a margin was during Western University in Ontario — and Brian Borowski was a volunteer.
During her career, she’s complicated how blind echolocators partisan tools of a differently new visible cortex when regulating their sonar, and investigated how echolocation adds to a toolkit of skills blind people use to navigate a world.
She’s also investigated either sighted people can learn to echolocate — and worked on a ability herself. Â

In her many new work, she’s been focusing on a really evil sonar “clicks” that, wholly independently, many echolocaters have schooled to generate.
These clicks are really brief — usually 3 milliseconds — and have really accurate frequencies.
This, she thinks, means that blind echolocators have exclusively detected a best sound that can be constructed for echolocation.
