Blind 7-Year-Old Boy Sees With His Ears

By Ki Mae Heussner © ABC News — Born without sight, 7-year-old Lucas Murray used to be so afraid of walking he wouldn’t take a step without his parents by his side. “He would walk, but he would hold our hands. Always,” said his mother, Sarah Murray of Dorset, England. “When he was younger, he wouldn’t even walk on a bumpy surface.” But now Lucas has become more mobile than his parents ever imagined, running with friends, playing basketball and jumping on a trampoline — all on his own. The incredible change, his mother said, is owed to a technique called echolocation, similar to the method used by dolphins and bats, that allows Lucas to paint a picture of his surroundings using sound he creates himself….

Blind boy uses his ears to ‘see’

© BBC, U.K. — A seven-year-old blind boy has been taught to “see” using his ears. Lucas Murray from Poole in Dorset has learned to use echoes to picture the world around him – similar to sonar techniques used by bats and dolphins. He clicks his tongue on the roof of his mouth and from the sound that returns he tries to work out the distance, shape, density and position of objects…. READ ARTICLE

Seven-year-old blind boy ‘uses echoes to see’

By Chris Irvine © The Telegraph, U.K. — Lucas Murray, a seven-year-old blind boy, is thought to be the first in Britain to use echoes to visualise his surroundings. Lucas, who was born blind, clicks his tongue on the roof of his mouth and uses the sound to gauge where objects are based on how they bounce back. By clicking, he can work out how far away an object is by the time it takes the echo to return. The intensity of the echo tells him the object’s size while the pitch tells him if a moving object is getting nearer or further away. He was taught the technique called echolocation, similar to sonar used by bats, by Daniel Kish, a blind Californian who founded the World Access for the Blind charity…. READ ARTICLE

Echolocation Allows Blind Humans to ‘See’

By Jessica Marshall, Discovery News, July 7, 2009 — Bats and dolphins aren’t the only animals that use sound to locate objects. Humans do it, too.  New research, which appears in a recent issue of the journal Acta Acustica united with Acustica, provides proof that humans can echolocate, a finding that is no surprise to members of the blind community….
