At work, the air conditioning grid is quite noisy (55 Db), too much air pressure. I asked to solve this to the technician but he told me there was not a solution since he cannot control air pressure.
The only solution I can think is to cover the AC grid. At this point I don't know if I should ask to do this or solve this by myself covering the grid one day when the office is empty.
My office colleagues haven't noticed this noise and I don't want to be the "problematic guy".
How should I approach resolving this? The noise is causing me difficulties in focusing and is quite annoying.
