If you're stuck with one engine, I think you need to address two issues -vibration transmission and noise absorption. Vibration isolation could reduce the transmission of vibration to the surroundings and an effective barrier could reduce the airborne noise.
If this is a stationary application...
Damping is beneficial in a vibration isolator because it reduces the amplification at resonance. However, there is a trade-off, because damping also decreases the vibration isolation at higher frequencies.
If you send me your e-mail address, I can send you a paper that addresses this in...
Carletes,
Current building codes take into consideration the height within the building in which equipment and piping are supported. If you have a FAX number, I can FAX you a couple pages which have the equations.

I think there are a couple reasons why you would not want to use a sine test as an alternate to random vibration:
1) Random vibration has amplitudes which vary with time. At each frequency, the amplitude varies based on a statistical distribution. If you were to determine a sine input at a...
