I wanted a window in the door. I was advised by my esteemed college to have a solid door since I have a camera inside. I listened and learned and SUCCEEDED ! Using a decibel meter I measured the noise of the makita inside the closed box at 94 decibels then I measured the makita from outside the box and it was 58 decibels. It looks okay and does the job. I did beef up the interior with my cheap version of mlv (rubber matting - aluminum flashing - rubber matting) and than a layer of ceiling tiles. That increased the noise reduction by 14 decibels over my last post in the "enclosure zoo". Thanks to Mark Bellon's advise and encouragement. The kirby vacuum cleaner is another issue, I'll just build a small impeller blower along with the small cyclone and replace it. That noise is too loud even with reduction.
