security through obscurity is not security
- 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 3 weeks 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.

according to the supreme court standing is no longer required
- Comment on Call to defederate from feddit.org over zionism 4 weeks ago:
they cannot change the law, but also they don’t have to follow the law because they aren’t within that country’s jurisdiction.
From what I’ve heard these are german laws and their instance is based in austria. Those are different countries.
- Comment on [deleted] 5 weeks ago:
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.

yankies? as opposed to yankees
- Comment on Maybe Trump's Presidency Will Make Everything So Awful It Will Facilitate Actual Positive Change Nationwide 1 month ago:
On the bright side, that saying is not a reflection of reality. A real frog will jump out of the pot.
- Comment on Oblivion remake is... really making it apparent how outdated Bethesda is in its approach to making games 1 month ago:
Its not a quick cash grab, the remaster was in development starting in 2021. This release had nothing to do with tarifs.

$90 to replay a 8 year old wiiu game. Why would anyone?
- Comment on Chinese EV maker BYD says new fast-charging system could be as quick as filling up a tank 2 months ago:
so… how much did does the us government give its auto industry?
They gave us auto companies 81 billion between 2008 and 2014, and continue to subsidize the industry to this day.
pot meet kettle

…
biden basically did that already. ever noticed there are no byds on the road in the us?
i seem to recall it wasn’t an outright ban, but unreasonable tariffs on chinese evs specifically. a soft ban, but enough to be as effective.
- Comment on Why can't we go back to small phones? 3 months ago:
They make bad small phones that people don’t buy because they’re bad, then conclude its because people don’t buy small phones.
They make phones like the palm palm, the second phone you have to pair to your other phone, for those days when the big phone is too big. Also the battery didn’t even last a day. When it doesn’t sell they say its because it was small, not the everything else.
- Comment on YSK: Gas stoves cause cancer 3 months ago:
What heat source are you using? In my experience induction about matches electric kettles.
- Comment on YSK: Gas stoves cause cancer 3 months ago:
Yes, but…
Cooking itself also does this. If you are searing or frying that will also release dangerous particulates. Make sure you have and use a vent hood that vents outside the living space when you cook regardless of fuel.
I can say from personal experience of using every kind of home stove, that gas is both the worst and slowest. Boiling water for my morning coffee is fastest on induction, which takes about half the time as resistive or radiant electric, and gas takes nearly three times longer than that.
Though it might just be the american style of burner that directs the flame away from the center of the pan. I’ve not yet tried any other kind.
- Comment on France runs fusion reactor for record 22 minutes 3 months ago:
no. that’s thermodynamically impossible.
though it is true that fission and fusion are opposites, you cannot gain energy by fissing and fusing the same material. There’s an inverted bell curve where medium sized elements are the lowest energy state. You can get energy by making atoms more medium, fusing the smallest atoms or fissing the biggest ones. Doing the opposite costs energy.

I’d much rather they make California the 13th province.

What specifically do you think that OSM maintainers should be doing to stop this instead of maintaining OSM?

- Comment on Study of 8k Posts Suggests 40+% of Facebook Posts are AI-Generated 4 months ago:
Every study uses sampling. They don’t have the resources to check everything. I have to imagine it took a lot of work to verify conclusively whether something was or was not generated. It’s a much larger sample size than a lot of studies.
- Comment on Study of 8k Posts Suggests 40+% of Facebook Posts are AI-Generated 4 months ago:
I pretty sure they selected posts from a 6 year period, not that they spent six years on the analysis.
- Comment on Tesla pulls out all the stops as Cybertruck sales grind to a halt 4 months ago:
“niche market,” is a way of saying they made a bad product few want.
pickup trucks are hardly a niche product especially in the us
