Question

To make a sound louder, the sound should be _______.

  1. Mute
  2. Amplified
  3. Decrease
  4. None 

hintHint:

Loudness of a sound depends on its amplitude.

The correct answer is: Amplified


    • Loudness of a sound depends on its amplitude.
    • Loudness increases on increasing the amplitude.
    • Therefore, to make a sound louder, it should be amplified.
    • So, the correct option is b.
