You, Too, Can Learn Echolocation

The Narrative Fallacy writes "Wired reports that 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. Acoustic expert Juan Antonio Martinez at the University of Alcalá de Henares in Spain has developed a system to teach people how to use echolocation, a skill that could be particularly useful for the blind and for people who work under dark or smoky conditions, like firefighters — or cat burglars. 'Two hours per day for a couple of weeks are enough to distinguish whether you have an object in front of you,' says Martinez. 'Within another couple weeks you can tell the difference between trees and pavement.' To master the art of echolocation, you can begin by making the typical 'sh' sound used to make someone be quiet. Moving a pen in front of the mouth can be noticed right away similar to the phenomenon when traveling in a car with the windows down, which makes it possible to 'hear' gaps in the verge of the road. The next level is to learn how to master 'palate clicks,' special clicks with your tongue and palate that are better than other sounds because they can be made in a uniform way, work at a lower intensity, and don't get drowned out by ambient noise. With the palate click you can learn to recognize slight changes in the way the clicks sound depending on what objects are nearby. 'For all of us in general, this would be a new way of perceiving the world,' says Martinez."

  1. Have to be a daredevil to be successful at this by Walt+Dismal · · Score: 5, Funny

    Before the unfortunate accident where I was blinded by a radioactive cylinder that fell off a truck, I could not echolocate. But now I am a successful lawyer by day and a blind but superpowered crimefighter by night. You too can have superpowers but there is a sacrifice to be made. You must avoid Windows.

    This is exactly what I've been looking for: Something else to do while I'm sitting alone in the dark.

  3. I am a firefighter by Anonymous Coward · · Score: 5, Interesting

    ...you insensitive clod. ...and one can't hear much in a working structure fire other than one's SCBA, the sounds of the fire, and your buddy on the hoseline.

    Which is why we have flashlights and IR cameras mounted on our helmets.

    Echolocation can be learned, just not applied in every low-light environment.

  4. Wouldn't work for firefighters by Anonymous Coward · · Score: 5, Insightful

    This would be utterly useless for firefighters as they all wear SCBA which requires a full face mask. Further more your ability to hear those clicks are again reduced by gear over your ears, radio chatter and the often very dense smoke around you soaks up large volumes of noise.

    This would take serious adaptation to make it even remotely feasible for someone in that scenario. If you're on a hose crew you can just outright forget it all together.

    It's not really important that its new or not. Everyone bemoaning this article so far has done so because they "heard" of a few people doing it. Well that really doesn't help the masses. To do that you need a way to reproduce the technique for other people who could use to learn it. The point is they developed a system to TEACH it, not just the method of echolocation itself.
