Frequency of sound determines its _____ measured in _____.

amplitude: amplitude of sound wave determines its _____ measured in _____. ​

Answer 1

Loudness of sound is determined by its amplitude.

Loudness of sound is determined by its amplitude.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.
