Question

Define Sound intensity level​

Answer 1

Answer:

Sound Intensity Level (LI) is the logarithmic ratio of the sound intensity to the reference sound intensity, making the absolute W/m² (watts per metre-squared) levels more manageable, i.e. 0 to 140 dB, as the list below demonstrates.

Answer 2

Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. .Sound intensity level is a logarithmic expression of sound intensity relative to a reference intensity.
