  1. Transmitted
  2. Amplified
  3. Echoed
  4. Reverberated

Amplified

The correct answer is: Amplified


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

    • Echo and reverberation are based on the reflections of sound.
