vibration readings/octave center frequency
vibration readings/octave center frequency
(OP)
I have received a chart which is supposed to be a vibration plot. The y axis is labeled vibration velocity in mms. The x axis is labeled "One twelfth octave band centre frequency (Hz)".
I do not have a clue as to how to interpret the horizontal axis. I am used to seeing this axis as Hz. or CPM.
Can someone help me out?

RE: vibration readings/octave center frequency
If you aren't familiar with that then each bin runs from cf*2^(-1/24) to cf*2^(1/24) (I think) and contains all the energy in the linear spectrum between those two limits.
