I am mad about cellphone cameras hiding the processing they do, and I am glad about software that lets me control it and opt in and out, and I dictated this rant on insta so I am resharing the images here and will attempt to turn this into a useful text post on my blog in future, when my hand is working better 🤘👍

A Short Essay on Signal Reflections

The essay nobody asked for, but I've been reading about for around a week, and now can explain very easily and intuitively.

When electricity flows from a region with low impedance to a region with high impedance, a reflection of the signal passes back up the cable towards the source. This tends to make the most intuitive sense to people - after all, the high impedance region is easy to imagine as a traffic jam, and the ripple going up the line is just all the electrons having to slam their brakes. We've seen this before.

However, you get an identical ripple when going from a region with high impedance to a region with low impedance, which kind of mangles that analogy. You don't see traffic jams in regions where the speed limit goes up, just in places where it goes down.

And so for that, we're going to have to break the signal into two parts.

V=IR is bread and butter, but nobody accounts for those in time. Everyone does DC steady state analysis, and this is slightly weirder. So in a line with low impedance to high, you just look at how much V (voltage) you need to push the same amount of current (I). Since R is getting bigger, you now run out of voltage before you run out of current. So all the voltage gets used up, some of the current gets used up, and the current that no longer has enough voltage to get pushed forward can't enter the new material and thus bounces backwards up the line. The reverse happens with high to low. You now run out of current (I) before you run out of voltage (V) because R got smaller and energy must be conserved, so you get a voltage wave that bounces up the line. So any time R changes you have too much of either current or voltage and the extra gets sent back.

There are some weird implications to this! For example, a zero impedance ground would actually be hella noisy because it would accept 100% of the current into it, but reflect the entire voltage signal back. And an infinite impedance ground would eat the entire voltage field, but reflect 100% of the current back. An ideal ground for low noise needs to have the same impedance as the node its attached to.

Reason: I want to make stickers to put up on public transit etc because I'm a non-confrontational bean but I'm losing my mind. (I can't currently wear headphones to drown out this nonsense due to a concussion so I gotta listen to everyone else -_-)

[bodoniyambo]

Der ganze Raum voller Menschen, unzählige Gespräche von einem Ende des Raumes bis zum anderen. Dazwischen ich, die Leere zwischen den Worten suchend, Ansatzpunkt meiner eigenen Konzentration auf die Aufgabe, das wesentliche. Wortstürme ausblenden, ausschalten, ignorieren. Das Lauter und Leiser der vielen Stimmen verschwimmt in einem weißen Rauschen. Noch weiter in die Aufgabe, stärker fokussieren, das Rauschen wird zum Wispern. Und aus dem Flüstern fremder Stimmen tauchen eigene Gedanken auf, zögernd noch, allmählich mutiger werdend, präsentieren sie sich, formulieren Lösungsansätze, Optionen, Möglichkeiten.

Die Gedanken verwandeln sich in Bewegungen der Finger, zaubern Buchstabe um Buchstabe auf den Bildschirm, das Klappern der Tastatur erhebt sich zur Begleitmusik meiner Aufgabe, lässt das Rauschen in den Ohren endgültig verstummen. Weiterschreiben, nächster Gedanke, nächster Schritt, bis die Aufgabe gelöst ist. Zurücklehnen, durchatmen, die eigenen Gedanken im Kopf und ihre Musik verstummen lassen. Langsam kehren die Stimmen aus dem Büro zurück, nehmen ihren alten Platz in den Ohren wieder ein...

"Kommst du mit essen?" Ja, natürlich... Einen Moment noch...

How Effective Are Pollution Absorbing Panels in Reducing Air and Noise Pollution?

In today’s fast-paced urban environments, pollution is more than just a buzzword — it’s a growing concern that affects our health, productivity, and overall quality of life. As cities expand and industrial activity increases, two forms of pollution—air pollution and noise pollution—are especially problematic. Fortunately, Pollution Absorbing Panels offer a dual solution designed to mitigate both issues. But just how effective are these panels? Let’s explore.

✅ 1. Noise Pollution Reduction: Acoustic Performance at Its Best

Pollution Absorbing Panels are highly effective when it comes to noise reduction. They’re engineered with sound-absorbing materials such as mineral wool, recycled PET, fiberglass, or perforated wood composites. These materials are designed to absorb sound waves, reduce echoes, and control reverberation.

In commercial buildings, schools, hospitals, and industrial spaces, these panels can significantly lower noise levels by up to 60–90%, depending on the design and placement. Panels with a Noise Reduction Coefficient (NRC) rating of 0.75 or higher are considered high-performing in absorbing airborne sound. This means they’re ideal not just for reducing overall noise, but also for enhancing speech clarity and concentration in busy environments.

✅ 2. Air Pollution Absorption: Green Tech in Action

Some advanced panels go beyond acoustics and incorporate air-purifying technologies. These may include materials like activated carbon, photocatalytic coatings, or bio-based composites that trap or neutralize airborne pollutants such as VOCs (volatile organic compounds), dust, and nitrogen oxides.

Pollution Absorbing Panels used in outdoor urban areas—on roadsides, public transit shelters, and building exteriors—have been shown to reduce surrounding air pollution by up to 20–30%, depending on air circulation and environmental conditions. For example, panels using titanium dioxide (TiO₂) react with sunlight to break down harmful pollutants through photocatalysis, essentially turning harmful gases into less dangerous compounds.

✅ 3. A Dual-Purpose, Sustainable Solution

One of the greatest advantages of Pollution Absorbing Panels is that they serve both functional and environmental roles. Not only do they make spaces quieter and more comfortable, but many are also made from recycled or sustainable materials, supporting eco-friendly construction practices.

Moreover, their ability to improve indoor air quality while reducing noise makes them a smart investment for LEED-certified projects, wellness-focused offices, and public infrastructure projects aiming to meet ESG (Environmental, Social, Governance) goals.

Conclusion

Pollution Absorbing Panels are more than just a trend—they're an effective, science-backed solution to two of the most pressing urban challenges: air and noise pollution. Whether you're designing a quiet office space or improving air quality in a busy public area, these panels provide real-world impact in both performance and sustainability.
