But "Hey, how about that game last night!" behind me and...
LizardBrain: "pattern identified: human speech. Attempting to parse...colloquialisms not found...setting parsing process to 'high' priority...audio sensitivity set to 100%."
ConciousBrain: "nooooo, I don't give flying shite about the SeaPigeons! Trying to work here!"
Working in an open office where the main language is a language that you understand well, but not natively (my every day life in Germany): you spend a ton of cognitive energy tuning it out, because your lizard brain insists on having that surrounding speech parsed first, just in case it has something to do with your work, because every so often, it absolutely does.
Working in an open office where you have absolutely no comprehension of the language (two weeks in Seoul): amazingly productive, because the lizard brain doesn't even bother.
Additionally, I have a really hard time focusing without _any_ music. Typically I need some beat to be able to get in the zone at all. It doesn't matter what the beat is - EDM, ska, soundtracks, lo-fi beats to study to, but there needs to be something.
Me, I can deal with sound in general, and I even like to listen to music while I work. What really messes me up is words - people talking, music with lyrics, stuff like that makes it very difficult for me to get my work done. Strong rhythms are also a bit of a challenge. So the sounds of people walking are tricky, my mechanical watch needs to go into a drawer if the room is particularly quiet, and the music generally needs to be something classical.
But there's also a threshold where there's so much cacophony going on that my brain just gives up and tunes it all out, and I'm back to my productive zone. When my coworking space is starting to get a bit too noisy for me to concentrate even with my headphones on, I typically deal with it by packing up and going to a nearby coffee shop that I can trust to always be busy.
