A doubling of frequency is an octave, cos that's how our hearing perceives an 'equal change' that's why the X axis of a frequency response graph is logarithmic.
Musically there may be some very slight variations on this.
Again..this is just a vauge recollection..

The crystal ball is clouding over.

.. Please insert another coin.

The octave is the variation between frequency f and frequency 2f. There are eight white notes between "middle C" and the "next C up" on the piano, and that's where the name can be seen; the "next C up" is 2x the frequency of "middle C".

Oh, yes. Please keep off the "loud pedal", by not using Caps Lock when posting.

Audio bandwidth - That is the frequencies which a normal person can hear. (from low to high)

I forgot what the limits are because I could not hear it.
