Question

Loudness distinguishes a feeble sound from a loud sound of the same frequency.

• A. True
• B. False

Answer 1

The correct option is A True

1. Loudness of sound refers to the intensity of the vibrating source producing it.
2. The intensity of sound depends upon the amplitude of the sound wave. Thus, the loudness of the sound also depends upon the amplitude of the sound wave.
3. Loudness of sound depends on the distance between the sound source and the listener.
4. The surface area of the vibrating body also affects the loudness of sound produced.
5. Thus, we can say that loudness is the characteristic of sound which distinguishes a feeble sound from a loud sound of the same frequency.

Thus, the given statement is true.
