Noisy, but Colorful!

Red noise helps you focus, pink noise helps you sleep, and blue noise gives you superpowers! Wait wait wait, hold on. What are you talking about? How can a simple noise change my life, and why are they colored?

The Telecommunications Glossary (it’s a Federal Standard, so you know it’s legit) formally defines 6 colors of noises. These include white, pink, brownian, blue, violet, and gray, and they’re named after their corresponding color from the same collection of frequencies in the visible light spectrum.

White noise

I’ll bet you’re all familiar with this one, the OG noise. As the first named noise, white noise, like white light, which is composed of all frequencies of visible light mixed together, is composed of all frequencies of audible noise mixed together. To us humans, that’s generally between 20 Hz and 20 kHz, and it sounds like TV static.

The main advertised benefit of white noise is that it masks all the random distracting noises from your surroundings. In essence, it helps you focus while you study or stay asleep while you’re sleeping. It’s claimed that if a massive truck speeds past your house in the dead of the night, its vroom vroom will be drowned out by all the frequencies already playing in your ears. But that means it basically blocks out ambient noise by overloading your system, which I personally find very unpleasant.

White noise is often confused with the hum of your hotel A/C or the drone of the large cafe, but those examples are actually where the other colors of noise come in.

Pink noise

Let’s take a look at pink noise, white noise’s twin sister. Pink noise is composed with the same idea as white noise, except that it decreases in intensity as frequency rises. To me, it sounds like an ocean, its constant, low rumble paired with the occasional high tones of breaking waves.

By the words of Cleveland Clinic, “pink is the new white,” and it solves my personal issues with white noise. While most people perceive white noise as uncomfortable static, they generally hear pink noise as a more flat and even sound, still able to mask the distractions of ambient noise. If you use white noise to help you focus or fall asleep, you might want to consider upgrading to pink.

Brownian noise

Also known as red noise for its similarity to pink noise, brownian noise, or brown noise for short, decreases in intensity as frequency rises with a steeper slope than pink noise.

This one is by far my favorite out of the three we’ve covered so far! Clearly, I have some sort of bias against the higher pitched spectrum of frequencies. What are your thoughts on this? Comment below!

Unlike the other 5 noise colors in this section, brownian noise is actually named after its counterpart in physics: brownian motion. Named after the Scottish botanist Robert Brown, brownian motion refers to the random motion of particles suspended in a fluid resulting from their collision with the fast-moving molecules in the fluid. How does this relate to brown noise? The orderly, y = -x + b frequency graph of brownian noise depicted above is actually the signal noise produced by brownian motion.

White noise, pink noise, and brown noise are the three musketeers of audio sleep aids. Because they cover the full spectrum of frequency, they’re perfect for masking ambient distractions. Brown noise specifically mimics the low roars of waterfalls and strong winds. If you’re a fan of rainymood.com, you’ll enjoy brownian noise.

Blue noise

Blue noise, unfortunately, does not give you superpowers. In fact, it lied to you, and it’s actually pink noise’s evil uncle! It’s weaker at the low end, and it grows stronger in intensity as frequency rises. Basically, it’s the opposite of pink noise, and it’s worse than TV static.

There’s no question as to why blue noise makes little to no appearances in “The Secret to Better Sleep” and “Life Hack: Improve Your Focus” blogs; I can’t even listen to it for more than 5 seconds, but it does possess an applicable use in audio engineering. It’s used for a process called dithering, which is when noise is added to a digital recording to reduce distortion and smooth it out. Regardless, the color blue may be soothing to the eyes, but the noise of blue is anything but pleasant.

Violet noise

I may be biased against higher frequencies, but somehow violet noise doesn’t sound all that bad to me. As you’ve probably guessed from the color, violet noise is basically the opposite of brownian noise; it contains high frequencies, like violet in our visible light spectrum. Without the conflict between high and low frequencies, isolated violet noise sounds to me like the pitter-patter of a nice warm shower. I’m not saying I’d let this noise lull me to sleep, but I’d listen to it over blue or white.

Gray noise

Finally, we have gray noise. According to its Wikipedia page, gray noise “is random white noise subjected to a psychoacoustic equal loudness curve (such as an inverted A-weighting curve) over a given range of frequencies, giving the listener the perception that it is equally loud at all frequencies.” This may sound trippy and overly technical, so I’ll break it down for you. Gray noise is just white noise, but upgraded to sound better to the human ear.

The best way to understand gray noise is to hear it yourself, so have a listen!

I’d say that’s a pretty accurate waterfall.

Here’s a nice sample comparison between the other five colors of sound I’ve mentioned today. Comment below: What’s your favorite color of sound?

When it comes down to it, we’re all humans with varying preferences. Some of you out there might be complete weirdos who bop to blue noise on a regular basis or otherwise enjoy a late night installment of 4 minutes and 33 seconds of silence, but you do you. In the end, the most effective life hack to improve your study focus or better your sleep and life in general is to use whatever tools you’re most comfortable with. It’s all personal preference!

Help Wanted

So, come November 22, my Latin class will be hosting a “Day of Poetic Enchantment” in the NPAC. Now, this event was piloted by my class last year, lasting for around the first half of school. Each participating student chose one poem (or a few if you’re into that) to read to a sparsely populated audience consisting mostly of other Latin students with a few enthusiastic parents dotted about.

When it was your turn to go, you had to awkwardly climb over and around your neighboring friends to reach the steep, unforgiving metal stairs leading up to the left stage (facing the stage), all the while with the eyes of the audience drilling a hole in the back of your head, with the thought of how embarrassing it would be if you were to fall. As you know, the NPAC stage is quite wide, spanning the entire front of the auditorium, but our performances were confined simply to a podium on the right-hand side of the stage (now facing the audience), with a backdrop slideshow presented behind. 

After that brief but taxing transition, you give a short introduction of your poem, including its title and author, and delve straight into its juicy contents.

But yeah, I’d say it was a pretty pleasant experience overall. Last year, I read this poem I’ve pasted here for you below from poetryfoundation.org.

by Christina Rossetti

 

What is pink? a rose is pink

By a fountain’s brink.

What is red? a poppy’s red

In its barley bed.

What is blue? the sky is blue

Where the clouds float thro’.

What is white? a swan is white

Sailing in the light.

What is yellow? pears are yellow,

Rich and ripe and mellow.

What is green? the grass is green,

With small flowers between.

What is violet? clouds are violet

In the summer twilight.

What is orange? Why, an orange,

Just an orange!

 

Yeah that poem got a few laughs….

 

This year, things are a little different. Not only will each of us be reading a poem to entertain the audience, but a piece of prose as well! How absolutely exciting. So of course I chose to prose a throwback to my short story from a couple weeks back, Mark Twain’s “The Celebrated Jumping Frog of Calaveras County.” Sadly, Magister Joyce capped the word limit on our prose pieces to 250 words each, which most of Twain’s great paragraphs surpass, so after hours of scrutiny on how to cut down on the introduction of Jim Smiley or his lost bet, I decided to instead go with the short but arguably sweet passage I’ve pasted for you below.

Thish-yer Smiley had a mare the boys called her the fifteen- minute nag, but that was only in fun, you know, because, of course, she was faster than that and he used to win money on that horse, for all she was so slow and always had the asthma, or the distemper, or the consumption, or something of that kind. They used to give her two or three hundred yards start, and then pass her under way; but always at the fag-end of the race she’d get excited and desperate- like, and come cavorting and straddling up, and scattering her legs around limber, sometimes in the air, and sometimes out to one side amongst the fences, and kicking up m-o-r-e dust, and raising m-o-r-e racket with her coughing and sneezing and blowing her nose and always fetch up at the stand just about a neck ahead, as near as you could cipher it down.

Quite hilarious.

 

But of course what you all came here for, in spite of yourselves, unaware, was the namesake of this blog post, the poem I’ll be reading to accompany this prose in my “dramatic” reading. In my arduous quest to find a suitable poem, I scoured through numerous websites. Poems.com, poets.org, even our blue poetry packet and past poems I’ve read in Latin! But in the end, I fell back on the most reliable of them all: poetryfoundation.org, of course, where I found “Color.”

I was originally looking for something seasonal, but after finding an abundance of turkey poems either too lengthy or confusing, I decided to move on to the subject of Christmas—hey, at least it’s past Halloween. It was thus that I stumbled across, and discovered, this:

 

Help WantedImage result for help wanted

by Timothy Tocher

 

Santa needs new reindeer.

The first bunch has grown old.

Dasher has arthritis;

Comet hates the cold.

Prancer’s sick of staring

at Dancer’s big behind.

Cupid married Blitzen

and Donder lost his mind.

Dancer’s mad at Vixen

for stepping on his toes.

Vixen’s being thrown out—

she laughed at Rudolph’s nose.

If you are a reindeer

we hope you will apply.

There is just one tricky part:

You must know how to fly.

 

What absolute poetic genius. Feel free to clap at your computer screen as you sit here reading my blog; nobody will judge you. Not only does Tocher perfectly balance a strict rhyme scheme with his sense of humor, but its chant-like read in fact enhances the hilarity of his poem; and, furthermore, he paints an amazingly amusing picture of a harsh alternate reality in which Santa’s reindeer are indeed not immune to the irking ailments of time.

I’m not sure exactly what made me click on a Christmas poem titled “Help Wanted,” but I’m sure glad I did. I guess the moral of the story is if you ever need a poem, pay a visit to poetryfoundation.org, and you’ll be sure to strike gold when you least expect it.
