trust me, bro:
here is the receipt.
the claim

A sound twice as loud corresponds to a tenfold increase in acoustic power.

the verdict
COMMON KNOWLEDGE
Legacy classification; evidence review pending
Recorded sources
no sources on either side

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that a sound twice as loud corresponds to a tenfold increase in acoustic power?

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).

Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked

The analysis

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.
