Another source of vibratory forces is Acoustical Vibration. Acoustical Vibration is created by pressure waves reflecting off of surfaces in piping. Typically these waves are created by reciprocating compressors. The frequency of this vibration needs to be compared to the natural frequency of the overall system.

Let's say that beyond the 50th mode you should go to a propagative analysis.
But that's not a law, just an advice. There are sonic sources that can excite the low frequencies of mechanical structures, for example.
But I'm sure that someone will give you a more precise answer.

"Mechanical Vibration is created by rotating equipment that is not balanced."
This of course only applies to periodic forced vibration; not all vibration is forced, nor, for that matter, periodic.

Not all noise or vibration control is control of the source; in fact, probably little of it is.
In many if not most cases, you find yourself treating the path or applying damper or absorber to "fight the symptom."
Sorta like having a cold - you try to reduce the fever or the headache, not having any effective way to defeat the virus.

Like I said: applying suitable damping is the most simple you can do :)
