No they are not the same as you infer. They are very different. And I didn't refer to mechanical vibration as waves. However I will now in terms of properties.
Mechanical vibration can be transduced into acoustic waves and visa-versa.Mechanical vibration can exist in a vacuum where acoustic waves cannot. The classic example of a bell ringing in a vacuum chamber; the bell vibrates mechanically, but there is no transduction into acoustics waves since there is no air.
Mechanical vibration is mostly expressed as transverse waves, sometimes surface waves and sometimes longitudinal waves.
Acoustic waves are exclusively pressure waves and are almost always longitudinal waves.
Again, the reduction of energy of mechanical vibration is damping.
The reduction of energy in acoustic waves is dampening.Two different terms for two different types of energy state changes.
By the way, reduction of energy in an electromagnetic wave is called loss.
All of these energy transfer modes and the reduction of energy in each can be referred to under the broader term, attenuation.
So feel free to use attenuation, it's much less specific or apparently less problematic. :-)
