What is the difference between Log & Octave in Y-axis options of "Acoustic Power" graph

After creating graph of "Acoustic Power" with Nastran OP2 files-Sort2 Results

It seems the value of Y-axis in Octave is same as Log.

In such a graph, the only difference between log and octave may be the axis tags.

You can see the differences in the tags when changing to 1/3-octave or 1-12 octave axis.

However, octave band axes should only be used in a frequency axis and are typically used together with octave band summation.
