Definitvely not, Robin.
there is often confusion with the 3 dB, because 2 added Audio Signals with
the same dB level will result in a 3 dB higher level. But two same siganls
do not result in doubling of loudness, a fact that was already known by the
organ makers. Also 2 strings do not sound as double as one, it raise only ~
to1.3 of loudness level. Sometimes you find tables where 10 dB is double
loudness, that is due to a  investigation in the fifties done by Stephens.
In later investigations (Warren, 1970) has been found that loudness doubling
is about the 6 dB. But this is also somewhat frequency dependent.
