Excerpts from Paul Davis's message of 2010-07-21 19:26:40 +0200:

I think the word loudness is a problem here. Afaik it usually refers to
how it is perceived, and twice the amplitude doesn't mean twice the
perceived loudness. It may mean twice the sound pressure level, energy,
or intensity (if we ignore analogue anomalies, as you wrote in some other
answer).
It may be nitpicking, but I found it important to differentiate between
the physical phenomenon and the perception. I like Musimathics by Gareth
Loy for the good explanations and clear use of terms. It actually
succeeds in explaining everything in clear and easily understandable
terms, I can recommend it for the writing style alone.
