How do you block distraction if you work in an open space and people around you are loud or don’t care about interrupting you?

I noticed that i can concentrate better by using youtube mixtapes with piano sounds or bossa nova music. So whenever i want to enter in the zone, i have some big headphones on and people will get the clue that i can’t be bothered. Ot takes some practice and some people will be annoyed at first, but in time they will get used with your habit

Noise canceling headphones if applicable. I work in manual labor positions and can get away with headphones. If it isn’t an option then maybe just have a talk with your coworkers.
