Question

Loudness of sound is determined by __________ *

Answer 1

Answer:

sound waves

Explanation:

The loudness of sound is determined, in turn, by the intensity of the sound waves. Intensity is a measure of the amount of energy in sound waves. The unit of intensity is the decibel (dB).

Answer 2

Explanation:

The loudness of sound is a phenomenon of a sound depending on the amplitude of the sound wave. If the amplitude of the sound wave is large, then the sound is said to be loud. The loudness of sound is directly proportional to the square of the amplitude of vibration and it is expressed in decibel (dB).
