We installed the vibration isolation for the OMC GV complessor, from 13:00 to 13:30 JST.

2hour period noise looks to be reduced well.
Thanks for your efforts! By the way, judging from the photos of the original klog post, the treatment you did was to put rubber sheets under the OMC GV compressor, right?
The BNS range would be determined around 100-1000Hz, and I guess vibration transfer in these frequency range would be mainly due to air, or in the other words, sound (like "sou-on", in Japanese). Is it possible to construct sound-proof walls around the compressor? The rubber sheets maybe useful to reduce vibration transfer at low frequency range ("shin-dou", in Japanese), but not for sound.
Our work were
- to put rubber sheets under the OMC GV compressor [for ground vibration]
- to cover the the OMC GV compressor with a blancket [for sound]
We are also discussing about sound-proof walls : https://www.hitori-shizuka.jp/products-and-service/partition
