Yes, linearity is relative, and it can be confusing. But usually, the one 
called linear is the amplitude ; the square of it is called quadratic ; 
and the log of it is called logarithmic.

If you have a logarithmic scale and call it amplitude, both the linear and 
quadratic scales have to be renamed to exponential scale, as do all other 
power scales. Then you can't distinguish them by name anymore, unless you 
start stating the base. This scheme is self-consistent but not used in 
practice.

C'est tout.
