  • 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.






  • The attack was done by the “yemeni armed forces” which is the official military of yemen.

    However, yemen has been in a civil war since 2014, with command of the military split between the government and the hoithi rebels.

    The spokesperson who took credit for the attack in the article, yahya saree is described by wikipedia as being part of the houthi faction.

    This seems to be much less of an official yemeni military action than the text of the article might lead you to believe.





  • 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.
