@koz i wonder how much people have tried to fix that. there are some techniques like blade shapes, or bigger blades, or even going full ham with metamaterials https://www.bu.edu/articles/2019/making-the-world-a-lot-quieter/

@jamie peltor makes some lovely hearing protection. i tried a procase last year but it was just too small for comfort.

  BU Engineers Develop New Acoustic Metamaterial and Noise Cancellation Device
  
  from Rachel Franklin
  
  Boston University engineers have created a sound baffle that isn’t a barrier at all, but instead an open conduit that allows air to pass through. Such a feat was only possible by developing a synthetic material with the special ability to cancel sounds but not air flow—an acoustic metamaterial.

  @jamie Sounds familiar. In my case it's mostly fan noise, when it's not the XPlus-3's shitty motor resonances at low speeds.

  According to a decibel app, my printers are about as loud as a vacuum cleaner about a meter away
