. The loudness of sound is determined by the

A: amplitude of vibration

B: ratio of amplitude and frequency of vibration

C: frequency of vibration

D: product of amplitude and frequency of vibration

Best Answer


  • Loudness of sound depends on intensity of sound waves. It can be determined by the given formula, L = 10log10 (I/I0) (where I is the intensity of sound waves and L is the loudness)
  • Since, Intensity of the sound waves depends on its amplitude, therefore, Loudness depends on amplitude of vibration.

Final answer:

Hence the correct option is A, i.e. amplitude of vibration,
