The perceptual correlate of frequency is measured in which unit?

Explanation:
Frequency is how fast a sound wave repeats each second, so it’s quantified in hertz, meaning cycles per second. In hearing, this physical rate relates to pitch—the higher the frequency, the higher the pitch. The other options gauge aspects of loudness or intensity: decibels measure sound pressure level, while phons and sones are perceptual scales for loudness. Therefore, hertz is the appropriate unit for measuring frequency.
