Question

Define intensity of sound. How intensity of sound is determined

Answer 1

Answer:

Explanation:

Sound intensity level also known as acoustic intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter

Answer 2

Answer:

Explanation:

Sound intensity is defined as the sound power per unit area.

... The most common approach to sound intensity measurement is to use the decibel scale: Decibels measure the ratio of a given intensity I to the threshold of hearing intensity, so that this threshold takes the value 0 decibels (0 dB).
