Question

Large amplitude of sound vibrations will produce

• A. Loud sound
• B. Soft sound
• C. Shrill sound
• D. Feeble sound

Answer 1

The correct option is A

Loud sound

Explanation for Correct Option:

Option (A):

1. Loudness is a subjective aspect of sound that corresponds to the magnitude of the auditory sensation of sound in the ear ordered on a scale running from soft to loud.
2. Loudness increases or decreases as the intensity increases or decreases.
3. We know that intensity is directly proportional to the square of the amplitude of the sound wave.
4. Hence large amplitude of sound vibrations will produce a feeble sound.

Explanation for Incorrect Option:

Option (B):

1. Sound with less intensity will produce a soft sound.
2. We know that intensity is directly proportional to the square of the amplitude of the sound wave.
3. Hence large amplitude of sound vibrations will not produce a soft sound.

Option (C):

1. Shrill is nothing but a high-pitched sound.
2. Pitch is another subjective aspect of sound that is perceived by the judgment of the brain.
3. It is mainly determined by the frequency but is not the same as frequency.
4. Hence large amplitude of sound vibrations will not produce a shrill sound.

Option (D):

1. Feeble is a sound that has low volume or loudness.
2. Hence large amplitude of sound vibrations will not produce a feeble sound.

Hence, option A is correct.
