Microphones and the human voice →

This is a well written article about the human voice, and how microphones really work in terms of capturing it. Even if you read this and plan to forget everything—you’ll come out *way* ahead when recording your and your guests’ voices.

Facts about speech intelligibility

slip:4udami1.

It’s full of insightful information, about the human voice:

…the voice changes spectrum in almost any other position than when we approach the speaking person with our ear – or microphone. Each position on the head or the chest has its’ own sound color – or timbre. For instance, the spectrum of speech recorded on the chest of a person normally lacks frequencies in the important range of 2-4 kHz. This results in reduced speech intelligibility. If the microphone does not compensate for this you should make corrections with an equalizer.

Important frequencies:

The important frequencies in non-tonal (Western) languages are illustrated by the diagram below. Here, the frequency band around 2 kHz is the most important frequency range regarding perceived intelligibility. Most consonants are found in this frequency band.

…and about what affects intelligibility in a reproduction of the voice:

A lot of research has been carried out in this area. In general, the results demonstrate that:

1. Optimum speech level is constant when background noise level is lower than 40 dB(A)
2. Optimum speech level appears to be the level that maintains around 15 dB(A) of S/N ratio when the background noise level is more than 40 dB(A)
3. Listening difficulty increases as speech level increases under the condition where S/N ratio is good enough to keep intelligibility near perfect

Furthermore, the 1-4 kHz frequency range should be “kept clear”. When, for instance, adding music as background for narration, a parametric equalizer cutting the music 5-10 dB in this frequency range will improve intelligibility.

Responsibility →

In an increasingly interconnected world, finding focus and enabling time to do work is becoming harder and harder. Demands are outstripping our capacity at an alarming rate. It’s time to start thinking about how we work.

It’s not “time,” it’s far past time. But the key point of the article, (which is itself simply a pull-quote hyper-summary of a book I’ve not read,) is:

Personal responsibility.

That’s it. That’s the magic sauce. Where I’ve found success has only ever been where I took personal responsibility. And I’ve chosen my language carefully in that sentence. There are places where I took personal responsibility and still did not find success; in some cases I’ve found outright failure. But in absolutely no case was I ever successful without taking personal responsibility.

The team must consist of three sorts of specialists, he says. Otherwise the revolution, whether in politics or the arts or the sciences or whatever, is sure to fail. The rarest of these specialists, he says, is an authentic genius — a person capable of having seemingly good ideas not in general circulation. “A genius working alone,” he says, “is invariably ignored as a lunatic.”

Meta: Copy-paste-and-search if you want to read the entire, surrounding passage. As a creator of content myself, I decline to copy and paste the much longer passage as many others have.

This passage from Vonnegut is brilliant, but it makes me a little nervous. Am I the genius? …or more likely, the lunatic? Perhaps I’m one of the other two specialists. Or worse, I’m not any of the three.

Nothing Fails Like Success →

There are internet companies (like Basecamp, or like Automattic, makers of WordPress.com, where I work) that charge money for their products and services, and use that money to grow their business. I wish more internet companies could follow that model, but it’s hard to retrofit a legitimate business model to a product that started its life as free.

ahahahahahahahahhahaahahhaaa! Sometimes I like to share stuff just because it makes me happy. (The stuff; not the sharing of said stuff, I mean.) I regularly talk about how this web site is a vehicle for my reflection—I’m quite often literally thinking through things. Writing, (tappity-tap-tapping on the keyboard here,) and writing, (scratchity-scritch-skratching with a pen on paper,) are two of the ways I figure out if the dross I regularly find in my head actually corresponds to reality.

When I read sentences like the ones I quoted above, I leap (sometimes literally) to my feet knocking over my chair in the process. It does my weary—deeply deeply weary it be—heart good just to read sentences like this. And I hope—not in the sense that I little value your ability to think and “hope” you’ll finally get what I’m saying; no. I only hope that sometimes, some of the things I share make you happier.

Numbered precisely →

If men could see their future years numbered as precisely as their past, what a flutter there would be among those who saw that their remaining years were few, how sparing of them would they be! With a fixed amount, however small, it is easy to economize; but when you cannot know when what you have will be gone you must husband your store very carefully.

Just because you can do something doesn’t mean you should.

~ Shane Parrish from, Gaming the System

slip:4ufoga1.

A long time ago, a social studies teacher had been giving the same multiple-choice, high school, final exam, every year, for [as I recall the story] decades. The catch was two-fold: First, each year he cut the exam into strips separating each question. Yes, by hand, with scissors. He then shuffled the strips, scotch taped them onto a new sheet which did have sequential numbers on it already, and then ran it through the mimeograph machine. There was no way to create a “cheat sheet” for this exam based on previous years (even if we could have gotten a previous test.) Second, the test was insanely long; hundreds and hundreds of questions long. In fact, it was—intentionally—impossibly long.

When he graded the exams, he noted the total number of questions each student attempted. To be clear: He’d note the number of the last question you answered. So if one skipped around, you’re doomed since you definitely get wrong, the ones you didn’t even try to answer. So the incentive is to start at the beginning and just work straight through; recall, they’re totally shuffled. He then computed the average number attempted, and that average was used as the total possible points on the test. If you scored above the possible points (unlikely, but possible,) the points got added to your semester’s total points. (So if you score +2 on the final, the first extra point, brought up your 9/10 quiz score to 10/10. That second extra point brought a homework up from 5/7 to 6/7.)

Have you spotted how you game this system?

Bonus question: I regret what we did, (there were 3 of us.) But, can you tell me why I regret it?

Thomas Droge and Brenda Kahn: Story, history, and self-perception

What are the ways in which personal narratives, self-perception, and mentorship influence an individual’s path to growth and transformation?

If you want to know someone, have a conversation with them. But if you want to know who they really are, have a conversation with their partner. Thomas Droge and Brenda Kahn share their story and how they’ve changed over the years. They explore the idea of our internal narratives and self-perceptions, finding your own way, and the human experience of time. Brenda and Thomas discuss ways to change the world and the importance of investigating your history.

I’ve been writing a memoir. And I had a really fascinating experience with it, because I got all the way through it, and realize that everything that I told myself about myself was totally not true. […] the stories we tell ourselves, literally, inform our lives in a way that have real consequences in the real world. And when you take a step back and look at yourself and decide, wait a second, you know, they actually did a lot of really cool things, you know— this was kind of amazing. So then I had to start the whole thing over again from this whole different slant.

~ Brenda Kan (38:24)

This conversation explores how personal stories and perceptions shape our lives and how reevaluating them can unlock growth. Brenda reflects on writing a memoir and discovering that her past achievements were much more significant than she initially believed, illustrating the transformative power of storytelling. Thomas complements this idea by discussing mentorship and the value of learning from both older and younger generations to stay connected with evolving perspectives.

And he said, for me, one of the things that I think people always miss in mentorship is that you need mentors who are younger than you, to share with you what’s changing in the world, and keep you connected to what’s happening. And mentorship is really a two way street, of the younger generation, connecting you with the world and what’s happening and showing you what’s changing from their point of view. To teach you so that you don’t get stuck in your static view of the world.

~ Thomas Droge (33:17)

The discussion also touches on movement practices, mindfulness, and self-discovery, connecting these to larger themes like time perception and narrative transformation. By examining personal experiences, they highlight the importance of self-awareness and adaptability in personal and professional contexts, as well as the role of mentors and shared knowledge in shaping these journeys.

Takeaways

Mentorship’s reciprocal nature — Younger mentors help connect older generations to evolving perspectives, making mentorship a two-way exchange.

Personal narrative’s power — Revisiting and reframing personal stories can completely transform self-perception.

Movement as insight — Physical practices like Tai Chi or Parkour help reveal inner narratives and foster growth.

The interplay of time and perception — Understanding time through different lenses offers tools for navigating personal transformation.

Storytelling and compassion — Approaching one’s story with compassion opens up new possibilities for growth and healing.

Seneca on Social Media →

Published September 23, 2020  ·  All posts on Sep 23

Over a billion people currently use Facebook — many at the cost of anxiety, lost honor, personal freedom, and certainly time. If asked why, however, many would reply, “why not?” The service is free, conventional wisdom tells us, so no matter how minor the benefits (which tend to orbit around a generalized fear of missing out), they’re still more substantial than the cost. But as Seneca points out, this assessment is misguided because it ignores the human toll of social media.

~ Cal Newport, from Seneca on Social Media – Cal Newport

slip:4ucabo33.

I generally try to suppress my urge to pounce on opportunities to talk about the well-known downsides of social networks. But a Seneca-CalNewport two-for-one is simply irrestible catnip for me. Here, Newport is referring to the value of one’s own time. That’s the human “toll” that so many people—as far as I can see at least—don’t factor in.

I think I am ready to give up fighting the fight; I’m done [or at least, I really should get a grip, and learn to be done] beating the drum about the evils of social networks. Know what I’m going to do instead? Double-down on creating things on the open web and let people decide what they want to do.
