Question

If the amplitude of the sound reaching person A is 5 units and that reaching person B is 10 units. Which of them seems to have louder sound?

• A. Person A
• B. Person B
• C. Both hear equally loud sound
• D. Depends on the distance from the source

Answer 1

The correct option is B Person B

The loudness of the sound depends upon the amplitude of the vibration of the sound. Thus, if the amplitude of the sound is more, the sound will be louder. If the amplitude of the sound is less, then the sound will be feeble. Thus, person B will have louder sound.
