Sound Intensity Level Calculator

Sound intensity is also known as acoustic intensity and is defined as the power (sound) carried by sound waves per unit area. In the below calculator select the one you wish to calculate, and enter the other two values. This is a simple online sound intensity level calculator to calculate the sound intensity/reference intensity/sound intensity level. The sound intensity determines the loudness of the sound, it is the amount of energy carried by the sound waves.

Use this sound intensity level calculator to know either the sound intensity or reference intensity or sound intensity level, by knowing the values of any two. Sound intensity is measured in decibels (dB). As decibel levels get higher, sound waves have greater intensity and sounds are louder.
