The loudness of sound is determined, in turn, by the intensity, or amount of energy, in sound waves. The unit of intensity is the
decibel (dB)
. As decibel levels get higher, sound waves have greater intensity and sounds are louder.

directly proportional to the frequency of the sound
. The unit of loudness is decibel.
What is difference between pitch and volume?
Pitch is a measure of how high or low something sounds and is related to the speed of the vibrations that produce the sound. Volume is a measure of how loud or soft something sounds and is related to the strength of the vibrations. Sound vibrations can be transferred from one material to another. below.
