With just a click of the tongue, anyone can learn to “see” with their ears, according to a new study of human echolocation\u2026.<\/p>\n
Several animals, such as bats, dolphins, whales, and some shrews, are known to use echolocation\u2014sound waves bounced off nearby objects\u2014to sense what’s around them.<\/p>\n
Inspired by a blind man who also navigates using sound, a team of Spanish scientists has found evidence that suggests most humans can learn to echolocate.<\/p>\n
The team also confirmed that the so-called palate click\u2014a sharp click made by depressing the tip of the tongue against the roof of the mouth\u2014is the most effective noise for people to use.<\/p>\n
Sound Training<\/strong><\/p>\n Daniel Kish, executive director of World Access for the Blind in\u00a0Huntington Beach,\u00a0California, was born blind. He taught himself to “see” using palate clicks when he was a small child.<\/p>\n Kish\u00a0is able to mountain bike, hike in the wilderness, and play ball games without traditional aids.<\/p>\n To better understand\u00a0Kish’s skill, Juan Antonio Mart\u00ednez and his colleagues at the\u00a0University\u00a0of\u00a0Alcal\u00e1\u00a0in\u00a0Madrid\u00a0trained ten sighted students to echolocate.<\/p>\n “It was very difficult to persuade some people to take part in the experiments, because most [of our] colleagues though that our idea was absurd,” Mart\u00ednez said.<\/p>\n The students were asked to close their eyes and make sounds until they could tell whether any objects were nearby.<\/p>\n <\/p>\n Quranic signs<\/strong><\/p>\n The Holy Quran refers to the importance of “hearing”<\/span>. So in many verses we found that the Hearing precede the “sight”<\/span>, Let’s see this verse, Allah Almighty says:\u00a0(And Allah brought you forth from the wombs of your mothers knowing nothing, and gave you hearing and sight and hearts that haply ye might give thanks.)<\/span>\u00a0[16\/78].<\/p>\n So we can say: The Holy Quran compatible with new researchs.<\/p>\n <\/p>\n ——————-<\/p>\n By: Abduldaem Al-Kaheel<\/p>\n <\/p>\n
