Question 21/XII - Relative level at the boundary between national
systems and the international chain
(New Question)

Considering

- that the Blue Book (Recommendation G.121) uses both a 0 dB point and
the conventional VASP as a reference point for sending and receiving
loudness ratings, the following Question should be studied,

Should Study Group XII convert all documentation to use the 0 dB point
as the reference on the international chain rather than the present
VASP?

If so, what changes will be needed to the G-Series Recommendations?
