A Correct answer
Explanation

The decibel (dB) is the standard unit for measuring sound intensity and amplitude. Coulomb measures electric charge. 'Hum' is not a standard unit. 'Cycles' refers to frequency (Hz), not amplitude. Sound amplitude determines loudness and is measured logarithmically in decibels.
