That's why it's only a rule of thumb. The sensitivity of our ears changes
quite dramatically across the frequency range, and the rate of change of
perceived volume with power also changes with frequency and absolute sound
pressure level. There is no specific number of decibels that equates to
doubling volume, unless a specific frequency, absolute SPL, and subject are
given.
