While this thread's focus is soundproofing, an enclosure can help manage sawdust and other debris. So, don't feel too much regret!FattyMatty wrote:I haven't made any official readings but this thing is very quiet, I kinda wish I had of purchased this before attempting to make a soundproof box.
It's like the thump of the bass notes that carry through walls while the high frequency stuff is filtered out.Philip wrote:I since learned/realized that different frequencies are damped differently. It seems the 2000Hz frequency is absorbed quite well so that makes the high reduction measured more understandable.
When I measured the sound from the other side of the door leading in from my garage, I was doing so after installing some weather stripping along the hinge side of the door frame. I'm not sure if it never had any or if it got torn out at some point, but there was a good 3-4 mm gap on that edge of the door. It wasn't straight through, but stayed about the same width as it dog-legged parallel to the door surface then 90 degrees to open to the inside of the house. That gap was big enough to let through a significant amount of noise. I didn't measure beforehand, but it went from loud enough to be "loud" one floor up (around 270 degrees of corners) to a little quieter than that right by the door and just audible upstairs. I'm not sure that the air compressor, with its lower frequency noise, will be affected as much, but still... I'm hoping that if I can get an equivalent amount of noise reduction from the enclosure, then it will be just audible on the other side of the door, and inaudible upstairs. Except, probably, for the compressor. Because it's a jerk.
