Discussion Overview

The discussion explores the concept of whether it is possible to "hear" with one's eyes, specifically through a device that transmits light interpreted as audio rather than visual information. Participants share their thoughts on the feasibility of such a concept, touching on neurological implications and sensory perception.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that it might be possible to create a device that converts visual signals into audio or haptic feedback, suggesting that touch might be a more effective medium than sound.
  • Others argue that significant modifications to the brain would be necessary, potentially involving synesthesia, to interpret visual signals as audio.
  • One participant mentions a case of altered sensory processing in a lab setting, where visual and olfactory senses were reversed, indicating that such changes might be feasible under certain conditions.
  • There is a suggestion that the question presumes the eyes would detect light, which would then be interpreted as audio, raising questions about the nature of sensory perception and interpretation.

Areas of Agreement / Disagreement

Participants express varied interpretations of the initial question, with some focusing on the neurological aspects and others on the technical feasibility of such a device. No consensus is reached regarding the practicality or implications of the idea.

Contextual Notes

Limitations include the need for significant brain rewiring and the unclear mechanisms by which sensory information could be transformed from one modality to another. The discussion also highlights the complexity of sensory perception and interpretation.

Ok, I am not even remotely a physicist. However I did have this thought.
Is it possible to hear with your eyes. Can a device be rendered in such a way to transmit light so that when the eyes saw it, that it would be interpreted as Audio not video so to speak.

Just general curiosity!

Any comments are welcome. Even the "Your a moron" kind
Thanks

Sure. Depends on how much and how intrusively you want to rewire the brain.

A less intrusive thing to do would be to set up cameras that see ahead, then convert that signal into an audio tone - or better yet, a haptic (touch) pattern. The reason touch would be better than hearing is that touch, like sight, is a 2-dimensional plane, whereas hearing is one-dimensional.
 
I might be interpreting your question a bit too literally, but you'd have to give your eyes a serious upgrade before you could see the vibrations in the air.

If you were to take his question literally, you will see that he presumes that what the eyes will be detecting is light ("..transmit light so that when the eyes saw it.."), but that it is only after the light is detected that it is interpreted as audio.

I'm pretty sure the brain would need to be re-wired as in a synesthete.

My oldest daughter sees numbers as colors. My youngest sees geometric shapes in everything.

Years ago a friend of mines mum who works in a drosophila lab produced a lineage where the visual and smell processing was reversed. They saw smells and smelt colours apparently though I have no idea how they did this or how they knew it was done correctly.

Hmm... It is possible that I might not have interpreted his question literally enough... :smile:
