What is the true advantage of plotting in terms of g^2/Hz?

What is the true advantage of ploting interms of g^2/Hz for random vibration? It's just not very intuitive for average human beings or even engineers.


Why can't we just plot in terms of absolute g^2 instead?


We have a sense of what g means.What is the true advantage of plotting in terms of g^2/Hz?
Plots are used to determine dampening characteristics, a second order function.


You really do want to know when the jello is going to stop jiggling?
