If reading aloud a children story, you may notice you are able to maintain an independent unrelated train of thought. While doing so, I notice that occasionally extra mistakes can "leak" into the story telling - e.g. you read a single word incorrectly, maybe substituting a word from your other train of thought.

When I was a kid, my dad (a physicist) would often read stories to me and my brother. He would sometimes fall asleep while reading, and we could tell when that was coming because suddenly our children's story would stop making sense and get filled with all these big physics terms.

ask any dj who doesnt use modern sync tools and they will tell u, u can follow 2 entire songs out of sync of eachother fine, it takes practice but your brain can get used to these kinda tasks. (ofc very unscientific here :D)

I’ve actually found that I’m able to process two speech streams and one music stream independently from those. At least for me, music seems to have a dedicated sub-processor of sorts.

There’s a big difference between processing multiple streams, and processing multiple streams simultaneously. You can achieve the former, without the latter, by doing time slicing. Spending a small amount of time processing stream A, then dropping that and processing stream B for a moment, then swapping back. Just like how a single core CPU can process multiple threads. Proving the brain is continuously processing an…

When I meditated a lot, I was able to sit in a cafe and listen to 3 conversations without switching and be able to understand them and remember them all. It happened to me few times. Also, once, sleeping in a tent, a voice from a dream interfered with sound of raindrops and became distorted and I woke up scared only to quickly get what just happened.

Not sure why you are downvoted. Well it probably doesnt require meditation because split attention is somewhat common here. My mother can follow multiple discussions like have a phone conversation and understand what I tell her. In general I can't.

So a bit harder for me. I can focus on work and follow some podcasts but not speak and at the same time listen to a full parallel convo.

I do believe brain to brain communication exists from experience too. People will be quick to call it schizophrenia and indeed it can be maddening because it evidently reuses your neurotransmitters for information propagation. That includes dopamine and can lead to the same issues some diagnosed people have, but actually a couple at the same time.

Without visual hallucinations but the brain gets a bit taken still, since it has to share processing. So it can induce adhd like symptoms, loss of phantasia, nucleus acumbens becoming nucleus incumbered :D, impaired motivation, etc.. But it is transient and you can argue it within yourself with some amount of relief. If you notice and start a loop of wondering where it comes from you are toast though.

Anyway, probably saying too much. You have to experience it. Probably someone playing with AI and neurochemistry. Still can't figure out the actual transport system. It does not make much sense from a wavelength point of view. Even if merely HF acoustic waves (since they can be more directed) not quite sure. Should ask whoever big galaxy brain created the havana effect... \sarcasm

At the same time people already know publicly how to decode brain signals and turn them into movements and Computer Interface actions. So the brain is not a complete blackbox. Some people might be further along...

Anyway... we will know eventually what is this all about..

The ability of the brain to do that gives me 15 min of quiet time to think about problems each evening. But you cannot follow the story in that mode, and the whole facade will collapse on a single innocent question...

In school, our teachers made us take turns reading the textbook. When it was my turn, I focused entirely on how my voice sounded, trying to match my cadence and tone to the punctuation. The moment I finished the paragraph, I would have to quickly re-read it in silence just to understand what it actually said.

I think I still can't read a non-trivial text aloud while trying to make sense of it at the same time. I need the two streams just for one text.

Oh yeah, I have been sleep deprived so much that the things that I said made no sense. I still formulated sentences but they did not have any meaning. In fact, I noticed this myself and I was like "fuck, what I just said made no sense". This happened a few times. It is a pretty interesting experience.

Airplane radios are generally broadcasting and receiving mono. There are modern headsets that can also play stereo, but only for onboard music or intercom purposes, if the plane supports it. But in planes with 2 radios you can usually configure their I/O individually. So you can listen (and also talk, although that makes sense less often) on two frequencies at the same time.

Yes of course, the transmitted audio would be mono. I meant one radio in one ear and another radio in the other ear, or if you mix them and they both play in both ears. But it sounds like they're mixed (talking over each other in a single audio stream).

Yes. I have never seen any system (planes or elsewhere) that splits multiple voice communication inputs so you hear different streams in different ears. How would that be different (let alone better) than having both streams in both ears? It's not like your brain can process each ear separately.

Not reading out loud, but I've caught myself a few times on reading and not processing that, because I was thinking about something else. Like I still did the reading, but straight to /dev/null of my brain

I think everyone does this. It reminds me of a possible related phenomenon. The act of remembering what you do takes a few extra brain cells, to enable the “recording function “. If you are on complete autopilot, doing a routine task, you will often forget to turn on the recording function. Like the other day I tried to remember whther I had run the dryer and realized it had been completely optimized out of my memory…

I get that while driving home. I've driven half an hour and then realise I've been thinking about something else the entire time and cannot recall anything about the journey.

The same is true for music, otherwise canons and polyphony wouldn't work.

That's not a good argument. First, music is not speech. It doesn't require linguistic processing. Second, you can hear chords instead of individual voices, so polyphony can be perceived as shifting harmony, and it usually is.
