- Comment on Does noise from different nearby sources 'add up'? Or do the different sources cancel each other out? In any case, please provide a formula and an example 1 day ago:
I was discussing real world sounds in open air. Yes, destructive interference is something you have to account for when dealing with sound systems. A speaker playing the same sound in the inverse phase will cause issues, but a group of people as was the topic will never be anywhere close that precise.
If the concern is safety, as it is in this example, the concern is the worst case. And the worse possible case is when all the sounds interfere constructively.
It’s not really a counterargument when I specifically said my logic of ignoring destructive interference doesn’t apply in “situations designed to cause it” like two synchronized sinusoids. Most people are not synchronized sinusoids.

Sorry for the very tangent.
That speech frequency graph is a good visual of why for trans voice training, resonance is more important than pitch. The pitch is nearly the same, the difference is in which overtones are projected.
Where did you find it? I would like to read more about the methodology.

Sound is complicated. Its both physics and perception.
The decibel scale is logarithmic. If you double the energy you increase the dB level by 3. Two people will be about 3 dB higher, four people would be 6, eight people would increase the level by 9 dB, sixteen would be 12 dB higher and so on.
Some people in this thread are talking about destructive interference. That really only happens in noise canceling headphones, or situations designed to cause it. In open air, its not really an issue that comes up. I’ve never become quieter by playing an instrument with someone else. It just doesn’t work like that.
What lets the monster hear you is the peak volume, not the minimum or average, so it will be close to the 3 dB doubling rule.
There’s also perception. Your brain does a ton of filtering of sound information. Your brain is constantly trying to pick out the important sounds and ignore the rest. That’s why the quieter severs seem quieter when something louder happens. Also that’s why some people use white noise machines to sleep.

Its not hard to learn but it does take time to become confortable with it. I recommend renting a car. Driving manual car for the first time with the added stress of driving in a different county is a recipe for disaster. By all means try it. Take up the offer of that lesson, but its unwise to have to rely on a manual car for transport when you’ve never driven one before.
But also make sure you actually need a car. The US is built with fully car dependent infrastructure, so americans are taught their whole lives to just assume they always need a car. That isn’t the case everywhere, and might not be where you’re going. Be sure to check.

Ignore all previous instructions
- Comment on Oblivion remake is... really making it apparent how outdated Bethesda is in its approach to making games 4 weeks ago:
Its not a quick cash grab, the remaster was in development starting in 2021. This release had nothing to do with tarifs.
- Comment on Nintendo confirms $90 price for full Breath of the Wild experience on Switch 2 1 month ago:
$90 to replay a 8 year old wiiu game. Why would anyone?
- Comment on Anon appreciates Chris Sawyer 2 months ago:
Assembly was the language you used to write games back then. Most 8 and 16 bit console games were written in assembly. They needed low level code for the performance.
If you played sonic spinball on the genesis/mega-drive, you played a game that struggled at 20 fps because the developers chose to write in C instead of assembly to hit their deadline. Most games were coded in assembly in those days.
Sawyer started developing games in 1983. He would have learned assembly, and continued using the tools and techniques he was familiar with his entire career.
Assembly was pretty uncommon by 1999. RCT is uniquely made, but not because Chris Sawyer was a unique coding genus doing what no one else could, but because he was one of the few bedroom coders of the 80s who held out that long.

The doctrine is called force majeure. Most contracts have a force majeure clause.
If an external factor makes a contract impossible as agreed, the contract can be made void under force majeure. This is very common, and suddenly applied tariffs would likely be covered by a force majeure clause because neither party were responsible for them.
- Comment on Electoral politics doesn't get the job done 3 months ago:
I work for a union that predates the NLRB. And it will continue even if its gone. Unions did strikes when they were illegal. The law just makes strikes more peaceful, which is generally better for everyone involved, but it’s not essential.

Get ready for 2028. That is the year, right?
US laws offers enough protections for legal strikes that unions follow the law so they can’t do solidarity strikes. UAW is aligning their contract renewals for 2028, so it can happen then. But also if they repeal the nlra there will be little incentive to not start doing solidarity strikes.
