Correct me if I'm wrong, but isn't 16 bit = 120db about the levels of gradations of sound? Even a 4 bit = 16 levels of sound pressure/SPL could go from 20db, 20+12.5=32.5db, 32.5+12.5db and so on until 120db.
Then, the important question is what's the minimum SPL difference perceptable (at a given spl level). That may well not be 1db.
That's not how it works. Each bit of sample size yields about 6db of SNR. If you amplify a source to 120db SPL that was recorded with 4-bit samples the quantization noise would be about 96db SPL.
What exactly do you mean by "see more than 60fps"? It's possible that 60fps video with full temporal antialiasing and low to moderate motion speed could fool untrained viewers, but if I'm allowed to move my eyes I can tell the difference between high frame rate video (simulated with strobing LEDs because of lack of suitable video hardware) and real-life motion well into the thousands of frames per second. This isn't an unusual ability:
I think people are also equating apples to oranges here. Vision is analog. There is no "DPI" or "FPS" that human vision can see. Some types of motion the human eye can perceive at thousands of "frames" and others it can only perceive at 60, some colors (green) and contrasts it can distinguish extremely fine detail in and other's (blue), it cannot. Ultimately it's variable and non-digital so it's never going to equate to some strict terms.
The audio, on the other hand, that reaches your ears comes from an analog source, even if it ends up digital in between. There aren't some resolution arguments to be made here, all that matters is that the output device can accurately reproduce the proper analog signal. Which has been proven time and time again, and that any simplification of said signal is imperceptible to anything but the most finely tuned listening devices (or maybe some special "golden ears" that the vast majority of audiophiles don't belong to).
We would want 10 bit screens because the research indicates that the dynamic range of human vision is around 90 dB or 1:1,000,000,000, which is alarmingly higher than even 1:1,024
According to Pantone, "Researchers estimate that most humans can see around one million different colours". So research says we only need 7 bits.
"Research".. sponsored by corporations, and peer-checked by scientific voting rings. A bunch of incrowd elitists who like to use jargon. Science and politics these days are pretty similar
I think a lot of your objections to 'science' are due to basic communication misunderstandings and taking things you heard second hand at face value as 'science'. It would probably help to decouple yourself from the notion that a pared down snippet heard from a journalist or on a website is actually what the studies are saying.
Where does this “can’t see more than 60 fps” rumor come from?
It’s trivially refutable by placing a 60 Hz strobe (e.g. old fluorescent light or even some aftermarket headlights) at the corner of your vision.
Also, for interactive systems, 16 ms is a large chunk of our reaction time. You need close to 1 ms response times (1000 fps) to approximate pen and paper.
Yeah, 60Hz on a CRT was more or less the minimum tolerable refresh rate, and 75-85Hz was noticeably better. And that's just for trying to display a static image without distracting flickering. Displaying smooth motion is a lot harder.
Try to do better than a simple google, maybe you'll actually stumble on real science which would help understand the difference between the linked claims about hearing and yours about vision
The topic of human vision and perception is complex enough that I very much doubt it's scientists who are making the claim that we can't perceive anything higher than 30-60fps. There's various other effects like fluidity of motion, the flicker fusion threshold, persistence of vision, and strobing effects (think phantom array/wagon wheel effects), etc, which all have different answers. For example, the flicker fusion threshold can be as high as 500hz[0], similarly strobing effects like dragging your mouse across the screen are still perceivable on 144hz+ and supposedly 480hz monitors.
As far as perceiving images goes, there's a study at [1] which shows people can reliably identify images shown on screen for 13ms (75hz, the refresh rate of the monitor they were using). That is, subjects were shown a sequence of 6-12 distinct images 13ms apart and were still able to reliably able to identify a particular image in that sequence. What's noteworthy is this study is commonly cited for the claims that humans can only perceive 30-60fps, despite the study addressing a completely separate issue to perception of framerates, and is a massive improvement over previous studies which show figures as high as 80-100ms, which seems like a believable figure if they were using a similar or worse methodology. I can easily see this and similar studies being the source of the claims that people can only process 10-13 images a second, or perceive 30-60 fps, if science 'journalists' are lazily plugging something like 1000/80 into a calculator without having read the study.
There's also the old claim [2] from at least 2001 that the USAF studied fighter pilots and found that they can identify planes shown on screen for 4.5ms, 1/220th of a second, 1/225th of a second, or various other figures, but I can't find the source for this and I'm sure it's more of an urban legend that circulated gaming forums in the early 2000s than anything. If it was an actual study I'm almost certain perception of vision played a role in this, something the study at [1] avoids entirely.
