IT IS nonsense, because the Audio Engineering Society has yet to define it, and if the AES does not recognize it, I call it nonsense.
They are the body that sets the standards in the audio field, and have been doing so for over 100 years.
To define a "reference volume", you would have to do so by setting out a long list of parameters within which that "reference volume" would apply, and then you would have created a definition that would only apply to a very specific situation. It would hardly be a universal standard! Its application would be very limited, and not useful in a general sense.
Some people say that "reference volume" is produced when the volume readout on a receiver says 0 db, but this is completely stupid. It is obvious that if you hook different speakers with different sensitivities to that receiver at that setting you will get DIFFERENT VOLUMES, not some "reference volume"...duhhh. You will also get different volumes at different distances from those speakers. The indication "0 db" on the receiver is just an AMPLIFIER GAIN SETTING that IS ONLY ONE OF MANY VARIABLES that determine actual VOLUME produced by the set of speakers that may be connected.
