    @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.
