Long time ago, while in his backyard enjoying a couple beers, this one guy asked me why the grass is green and not some other color. I had no idea. He explained: "the natural chemical on the cells of the surface of the grass blades absorbs every spectrum of color from the sunlight, except the green color. It bounces it off, so when we look at it, all we see is the green light coming at us." I in turn asked him: "Then what is the real color of grass?" We each drank 2 more beers in total silence.

There are actually a variety of noises like pink or brown noise, used by sound engineers.

[@anorcott]

We always used pink noise for “ringing the room”. As the electrician I could never tell the difference. 🤷

[@dvsmotions]

Pink noise is tuned for the human ear. It has higher amplitude on the low frequencies and a slight increase on high frequency. Always used for audio calibration on sound systems.

[@arkaitzcarrasco2216]

@@anorcott Pink noise is more similar to what are ears listen to. White noise is equal in the electric domain and pink noise is more equal in the acoustic domain as we perceive it, so it has the opposite curves in frequencies that are ears like to have.

[@fredrikjohansson]

I’ve always wondered if the first people getting color tvs were disappointed that the static was still in black and white..

[@olencone4005]

When I was just a little kid in the 70's, we only had a B&W TV. And every Saturday morning as I watched my cartoons, I would always wonder what they would look like in full color... and finally, many years later, my parents bought a color TV. And I was soooo disappointed when the very first shows I saw were a B&W Bugs Bunny cartoon and a B&W Abbott & Costello movie... I was totally doing a "wait, what...?" 🤣

[@lawrencedoliveiro9104]

Why is that? Because the colour-decoding circuitry in the TV needs to pick up a special component in the broadcast signal before it turns on. This is to avoid introducing a certain level of random colour noise into a black-and-white picture (imperfect analog circuits, don’t you know). So in the noise that the receiver picks up in the absence of a signal, there is nothing resembling this colour signal, so the colour decoder remains off.

[@AceSpadeThePikachu]

There's a variant of "white noise" called "pink noise," which is aptly named (by Neil's description of the origin of the name of white noise" because it partially mutes some of the higher frequencies, which results in it sounding softer and a bit less harsh on the human ear. Red noise is when you completely remove the higher tones leaving only the mid and bass tones, and it creates this really relaxing "wooosh" sound, like waves on a beach.

[@damon_aaron]

Also brown (Brownian), blue and voilet

[@kittycasino29]

@@AceSpadeThePikachu lmao 🤣

[@SamusSelf-Destruct]

So, I work in live audio, and we use something called pink noise to tune our speakers. It’s white noise, but the high end is attenuated so that you hear all the frequencies equally, since white noise tends to build up toward the higher end of the spectrum. It’s called pink because the light equivalent would be to attenuate the blue light.

[@morbidmanmusic]

He said all that in the video, but he messed up in the pink noise aspect.

[@StarTalk]

Thanks for the info!

[@lawrencedoliveiro9104]

Amplitude as a function of frequency (correct me if I’m wrong): White noise - constant Pink noise - 1/f Brown noise - 1/f² To get the power/energy density as a function of frequency, multiply each of these by f. What your ears hear is the energy, not the amplitude, which is why white noise seems dominated by the higher frequencies. So pink noise has constant energy over the frequency band.

[@lawrencedoliveiro9104]

These are all random noise signals, where a sample at any particular time shows no direct dependency on a sample at any other time. In computer graphics, we also like to use “noise” functions which are not really random, but always have the same value at the same point.

[@lawrencedoliveiro9104]

For example, Perlin and Musgrave noise functions are handy for producing various interesting textures on materials. A little bit of Perlin colour variation can turn a clean, immaculate-looking object into a dir

[@glenncurry3041]

White noise is all frequencies with equal energy at each frequency. That causes more energy in higher spectrums because of there being more frequencies closer together as you go up. An ultraviolet catastrophe for sound engineers because of too much energy that high up. Pink noise is all frequencies but the energy is the same per octave, or logarithmic distribution. So the per frequency energy goes down as the frequencies go up. This is more often what sound engineers use for speaker set up. And there are variations of it. Computers, digital devices can not generate a true white or pink noise because digital devices can not generate a true random number. (Explainer?) They can run a program that simulates one and resets at some point in time.

[@markgigiel2722]

It's very complex and Bose and Dolby etc. have patents on it. It's not about the sounds, it's about understanding human perception of sounds. That's why I dislike much of new music. Using computers and algorithms and autotune etc. take away the feeling. The very slight imperfections and purposely wrong timing to create a feeling, make it human. Ring Starr was a left handed drummer with a right handed kit. He explains why some hits were off. But they were consistently off every time and it was great.

Synaesthesiac here. Ironically enough, to me, white noise sounds sort like like a combination of dark green and black. The higher pitches have a brilliant, bright cyan kind of hue, but still not white. Not all those with Synaesthesia see the same colours with the same sounds/ tastes, etc. It’s not some fundamental truth we alone can sense. Still, though, pretty ironic!

Pink noise is incredibly common in audio applications, tbh moreso than white noise in a lot of situations. Pink noise is where all octaves are equal intensity rather than every frequency being equal. There are just so many more high frequencies than low frequencies that with white noise you're primarily hearing high end. Tuning a room with pink noise makes a lot less people hate you. There are other "color" noises as well, but pink and white are the only ones super commonly used.

There is a rotary phone a few feet from me for that very purpose. If I could bring back radio transmitted television, I would. Lastly, I believe no child should ever be given access to the internet until after they have learned how to find a particular book in a physical library.

There MIGHT be 3 kids in this entire nation at this moment that can locate a book in an actual library. And that is seriously being as generous as possible here. Kids think Earth is a plate, aliens built the great pyramids, and that LSD is perfectly safe. I'll tell you one thing for a definite fact... not one of those kids got ANY of that false information from library books or any state funded school outside of Florida. Those collections of absolute intentional ignorance came DIRECTLY from the uneducated and inexperienced being allowed unsupervised access to today's technology known as the internet.

I just finished his lectures "My favorite Universe" on Audible. The last lecture he goes off again on Hollywood depictions of aliens. Rightfully so. But more than once he brought up "Close Encounters of the third kind" and how did the aliens know the latitude and longitude coordinates for Devils Tower, Wyoming. I'll answer that one as bet I can. The aliens had a lot of human abductees on their spaceship including military men, pilots and sailors. They would have gotten the coordinates from them. That's how I think the aliens would have learned something about how we navigate on Earth. I would love to see Dr. Tyson work with Hollywood on a film where he gets input on what they look like.

I am not a physics, therefore can getaway with the rf related expression "noise floor" that not only includes roughly the same concept but easily goes beyond and below audible frequencies and conveys the same idea of low power multiple frequencies in the background.

Funny thing is - I at first never understood 'Roy G Biv' when people talked about the 'colours of a rainbow' in school, and never understood the way others drew them in school with all these extra colours. Same when light goes through a prism. It wasn't till I was much older I realized that it's something with my ability to see colours. What I actually see is essentially RYI - I see red, yellow, and 'blue' (or apparently the Dark Blue I see is Indigo?) when I see a Rainbow or light through a prism because they essentially are 'absorbed' in to the others when I look at them, even though in some case I can still see them separately. But I can't identify certain 'shades' properly - such as 'navy blue' from black, some 'oranges' all I see is red, all depends where the 'line' is if I see it, or the colour that would be left/right of it on a scale. It's like if there were 100 colours humans can see, I can only see maybe 75 of them. Which can really suck cause 'colour blind mode' for games and what not is no help for it.

In Britain, particularly in England the rainbow mnemonic is "Richard Of York Gave Battle In Vain". The "Richard" was a former king of England who's body was rather carelessly lost for several centuries before it turned up buried under a car park in Leicester.

My husband has a startalk tattoo above sir Isaac newtons crest. The startalk logo has starry night inside the logo because of Neil’s love for the painting

Chuck... I'm an old white man and in this woke age, everything else is being taken from us. PLEASE let us just have the noise! 😉

I've figured out how to change the stars by stopping hurricanes. Don't worry, I've technically already done the hard part and changed the stars. My parents were teachers and for almost 2 decades, they taught their students my constellation. Those kids will teach their kids. So on and so on. See, stars changed. I just need help to make it legit and with the rest. Need to get to Willie Nelson's house ASAP. No, I'm not kidding. Yes, I'm serious. I get 7 things and remember, crazy is a compliment. Will you please help?

I am a music producer and I use pink noise for mixdowns in music production. There is a brown noise as well. Wonder how those names came from

[@lawrencedoliveiro9104]

I think the term “pink” came from the idea of a colour in-between “brown” and “white”. “Brown” noise can be produced by a mechanism known as “Brownian motion”, which is the random jostling of atoms and molecules, which can be observed causing larger objects, like specks of dust, to move around under a microscope. Einstein famously used this phenomenon, in one of his three classic papers of 1905, to prove the existence of atoms, which had been considered as little more than some kind of theoretical abstraction before then.
