Probably bad for your hearing too (piefedimages.s3.eu-central-003.backblazeb2.com)
 

For reference, the loudest sound ever on earth was 180dB https://wikipedia.org/wiki/1883_eruption_of_Krakatoa

Fun fact. Adam West Batman has an audio communicator capable of producing "20,000 decibles', while this is only used to scare off a tiger, this would realistically be powerful enough to create a black hole and destroy the universe

20000 decibel, or 2 kilobel

yes, deci- is the si prefix for ^1^/10. the actual unit is the bel.

i am saddled with this cursed knowledge so now you must be too.

    Are you a fellow PAG/NAG calculator, too?

    More cursed knowledge (for them, probably not you): it's logarithmic so every 3dB increase is double the energy!

    When I was in my first year of college - 26 years ago - I asked a question about logarithms and was thoroughly, angrily (and, looking back on the event, probably justifiably) reamed out by another student about it.

    I don't think I publicly spoke up for the rest of that class.

    edit: Remove extra words.

    I'm gonna go out on a limb and say it probably wasn't justified to respond to a math question like that lol

    I think it was an overreaction in terms of its delivery, but I was homeschooled and started college early. I was the stereotypical socially inept homeschooler. The class was introduction to college algebra, which doesn't usually cover logarithms AFAIK; I brought them up unprompted during a quiet moment when the teacher was cleaning the whiteboard. I was curious about them because I had been reading my older brother's textbooks and found them interesting.

    The other student's complaint about me was that I monopolized the teacher's attention by sitting front and center and raising my hand for every question. Additionally she felt that I was trying to show off. At that point I was also very visibly younger than everyone else, which did occasionally annoy people. (This became less of an issue when I hit puberty and started growing a beard.)

    But I was oblivious to those kinds of things at the time and didn't realize I was having any kind of impact on anyone else in the class until the other student chastised me. Perhaps it was an overreaction, but the message was one I needed to hear, I think.

    Also, to their credit, that student did apologize to me, more calmly expressing the nature of their grievances; I apologized in turn and said that I would try to be less disruptive.
