My end goal is to find the effect of various variables through simulation, eventually reduce the noise by implementing the feasible ones. Experimental approach is definitely the better way, but it is not feasible to run such lengthy noise level tests in my lab for "experimental" purposes. Above that, there are just too many variables to isolate. 

Using vibration isolating supports was a nice observation. In fact, the effect of the stiffness of the rubber grommets used here is also another analysis I plan to conduct later on. That's another discussion. Changing the plate thickness might work but again, it is one of many of other variables. 

Effect of tightening torque on the bolts do play a role in the vibration of the compressor as analyzed by our technical experts, a stiffer compressor is prone to higher vibration. 

Using accelerometers has been considered as plan B, as I do not have direct access to it. Also, I believe similar questions will arise as to "How" to input that data as a boundary condition in a harmonic response analysis. 

Thank you for the tutorial on the tuning fork. I had taken a similar approach in conducting a trial simulation of the compressor, providing a "Dummy force" on it after going through other acoustics tutorials available in the ANSYS Learning Hub and other sources. Further study on it will go nowhere unless I figure out how to input the boundary conditions first, be in the compressor rps or the surface vibration data.
