Los ecos del comunismo primitivo: ecolocación

La ecolocación, como cualquier potencial humano, es parte del comunismo primitivo, comprendido como todas aquellas capacidades innatas o instintivas, que hemos desarrollado en comunidad, como seres humanos y más allá, en el tiempo, como seres animales y como seres vivos. Pensemonos como células, como cachitos de vida dentro de un utero muy grande de vida que es Gaya. Como matriuskas reconectándose entre sí y reconstruyéndose en perpetuo cambio, en el seno de un océano de sensaciones muy largamente (co)evolucionado: la sensosfera o consensosfera, o ecosensosfera si lo que deseamos es enfatizar los ecos y la ecolocación, que junto a la abducción, las neuronas espejo y la revitalismo neuronal, convierten de una vez "el mapa en el territorio", un territorio que ya mama sin complejos de "La Carne" merleau-pontiana, de la fenomenología de Husserl y de Maturana-Varela, de la biomusicología, de la sincronicidad de Jung, de la psicología de Williams James, de la biología cuántica.....

Echolocation to "see" with sound

Daniel Kish is a blind psychologist who uses echolocation to "see." In New Scientist, Kish writes about his experience of "echo vision" and how he teaches others to do it:
Although our programme has many facets, we are best known for teaching FlashSonar. Its ability to give blind people a way to perceive their environment far beyond the reach of an arm or a cane is fast being recognised by people who work with blind people and in other disciplines. We are the first to develop a systematic, comprehensive way of teaching it.

We start by sensitising students to echoes, usually by having them detect and locate easy targets, such as large plastic panels or bowls. Once they can do this, we move on to learning to recognise more complex echoes by comparing them to familiar ones.

For example, when facing a hedge, a student might say, "It sounds solid?" I might reply, "As solid as the wall to your house?" "No, not that solid," she might say. "As sparse as the fence of your yard?" "No, more solid than that," she might answer. Now we have a range of relativity to work with. "Does it remind you of anything else near your house, maybe in the side yard?" "Bushes?" she might query. "But what seems different from those bushes?" "These are sort of flat like a fence." Ultimately, students verify what they hear by touching.

the article overflows with coolness.

"I practised my biking skills by slaloming among rows of trees, clicking madly."

I vaguely remember a neuroscience lecturer telling us about the fun experiments they used to do with babies.

The one that impressed me the most was giving them little "clicker" backpacks that emitted a sharp "click" every few seconds. If the baby wearing that is blind (or sighted but in a dark room) they learn to explore and navigate by sound amazingly quickly.

It'd be really fun to try actually... I'll book it in for the week after learning to follow a scent trail, bloodhound style.

No no NO! Daredevil is supposed to be a LAWYER, not a psychologist! Fucking adaptations keep screwing up the source material.

I remember first discovering echolocation through the life of Ben Underwood, which was fascinating to me. Sadly, the young boy (also linked in the "previously" on this post) passed away in January just a week short of his 17th birthday.

Still has nothing on the Platypus though.

we need to get him underwater with a rebreather, diaphragms over his ears and some kind of click maker.

I have always been deeply impressed by this.

I always thought this was impossible for humans to do... of course, the sources that told me it was impossible had probably never bothered to go out and test this guy's abilities in the field. Goes to show me.

ben underwood died? that's a real bummer. i was pretty astounded and captivated by the doc about him i saw on youtube:

Makes me recall the CBC Quirks and Quarks episode about the "vOICe" program - software used to create sound landscapes that the brain can translate to images. Nowhere as cool developing your inner "bat sense" but still pretty fascinating:

for the last 1o years I have worked with first a chamber orchestra, and most recently an opera company. in both cases, my primary responsibilities have revolved around performance set-up and recording, which requires that hearing serves as my primary sensory input.
at some point fairly early on, my sensitivity to acoustic environments passed the threshold that separates ordinary from weird-science level, where I could denote objects and surfaces with a clarity that was frequently astonishing. I knew that there was probably nothing that actually changed per say, except that I was finally paying attention.

either that or you're a witch.

I've done enough walking around in the dark (long story) or my eyes closed (just for practice in case I ever lost my sight) that I am certain echolocation abilities can be learned. Not enough to catch a fly with chopsticks, but enough to move with some confidence without sight. Of course, memory of the space helps a lot, too.

I didn't know he passed away :(
