Can Reducing Vibration Alone Solve Noise Problems?

"The answer to whether reducing vibration alone can solve noise problems is: it might, if the noise is primarily caused by vibration (Vibration Induced Noise). However, if the noise originates from sources other than vibration (Airborne Noise), addressing vibration alone in that area will not eliminate the perceived noise disturbance."

A client inquired via phone about two cooling units installed on the second and third floors of a building. These units vibrate during operation, disturbing several employees working in the building. The question was: If only the vibration issue is addressed by using Vibration Isolators installed at the base of the machines, will the noise disturbance be completely resolved? (On-site inspection was not yet possible.)

The response is as follows:

1) If the noise disturbance primarily comes from vibration, or Structure Borne Noise, it may be eliminated.

2) However, if it's mainly Airborne Noise (including Reverberation), the vibration might cease, but the noise could still cause annoyance.
