Question

Name the characteristic of the sound affected due to a change in its amplitude.

• A. Loudness.
• B. Wavelength.
• C. Frequency.
• D. Waveform.

Answer 1

The correct option is A Loudness.

Amplitude is the size of the vibration, and this determines how loud the sound is. Larger vibrations make a louder sound.
The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the amplitude of vibration is greater, and the intensity decreases as the distance from the source increases.
Hence, loudness of the sound is affected due to the change in its amplitude.
