Alessandra Ali · Answer 1

Intensity

Explanation:

The intensity of sound is also called acoustic intensity. It is a power that carried by waves of the sound as per unit of the area. The SI unit of the intensity is watt per square meter. It is no the same as a physical quantity. Human beings are so sensitive about the sound pressure that is also related to the intensity. When we see the differences in the audio electronics the differences are called intensity differences but we can not sense the sound intensity, for this, we can have to use the microphone.
