No citation is needed as this is a well-established physical principle of psychophysics where a tenfold increase in acoustic power corresponds to a doubling of perceived loudness (a 10 dB increase equals a doubling of loudness).
The claim states a fundamental psychophysical property of sound (loudness doubles with a tenfold increase in power, or 10 dB). None of the retrieved papers specifically evaluate or test this psychophysical scaling law, making it a matter of common scientific knowledge. Per instructions, common knowledge claims are assigned the COMMON_KNOWLEDGE verdict with empty index arrays if no retrieved sources bear directly on the specific mathematical relationship.
