• Oh yeah if you’ve got equipment to cut wood accurately they’re dead easy - I bought the ones in my studio but I’ve seen plans/calcs around for the ‘right’ insulation. Mine are on brackets that stand them off the ceiling, as the air gap increases effectiveness.

    I was going to mention restaurants with no treatment - nothing worse than the sound of chairs and cutlery scraping with people getting louder and louder!

  • A friend is a brilliant carpenter and could probably mitre some wood for an accurate frame.

    Then there is still having to get “challenging” aesthetics past my partner, who may object.

  • If the fabric colour matches the ceiling, they can be pretty subtle (or you could light the gap with neon leds for a somewhat different feel)!

  • frame

    If the frame isn't too big it's an easy DIY job. Because the whole thing is covered they can just be butted against each other, then screwed and glued.
