alleryStart learning →Frequency doubles; amplitude is unknown. What follows?
ALower pitched; loudness unknown
BQuieter and higher pitched
CHigher pitched; loudness unknown
DLouder and higher pitched
Answer & Solution
Correct answer: C. Higher pitched; loudness unknown
Doubling frequency raises pitch, but frequency data alone do not determine loudness.
