No I didn't. Loudness and signal strength are not the same things. You
attempted to correct my statement that 10db is the measure by which
LOUDNESS is halved or doubled by claiming 3db was the correct figure.
Then I responded that 3db is a measure of something entirelty different
than LOUDNESS.

LOUDNESS is an AURAL phenomenon. It is *not* expressed as electrical
energy, and is best related by way of decibel expressions. Electrical
energy itself is expressed in terms like voltage, wattage, current, etc.
The two terms, "loudness" and "electrical energy" are not synonomous,
interchangeable, or linked in a linear one-to-one relationship.
