Let's put it differently. If you only had sound B, and you
were asked to position a similar sound X halfway between
total silence, and the level of sound B, wouldn't that be the
same as asking that sound X has half the loudness of sound
B, or as asking that sound B has double the loudness of
sound X?

I'd be *very* surprised if that would turn out to be true.
I bet that if B is A + 40 dB, X would turn out to be
close to A + 20 dB. And if B is A + 60 dB, X will be
close to A + 30 dB. In both cases A is very small
conpared to B (at most 1/10000 in power).
Ciao,
Transporting this to the audio domain, given two
similar
sounds A and B with a B having a higher level than A, you
could adjust a third one X so it appears to be 'halfway'
between A and B. If you do this with A much smaller than
B, would you expect X to be close to 'half a loud as B' ?
If A would be very close to silence, yes.
