Tyler G. Chris S. The instrument air compressor received different equipment isolation to (hopefully) mitigate noise during operation. The changes made were springs which deflected at a lower weight (approx .830" at 250lbs of load) as well as a soft silicone pad placed between the springs housing and the concrete slab. This task was completed at approx 8:45am

I have attached the spectrogram of the strain, where you can see the air compressor noise coming through - at first look, it seems it has not gotten better.
8:45 am would make it 16:45 in the attached image (right where the big red bar is).
