Question

The loudness of sound I is ____ to the loudness of sound II.

  1. >
  2. <
  3. =
  4. None of the above

hintHint:

Amplitude determines the loudness of the sound

The correct answer is: >


    • The loudness of a sound depends on the amplitude of vibration producing the sound.
    • The bigger the amplitude is, the louder and more intense the sound.
    • Therefore, loudness of sound I is greater than loudness of sound II.
    • So, the correct option is a.
