The decibel level of a sound with an intensity in watts per metre squared is defined as
The reference intensity is .
Step-by-step explanation
Step 1.
The deci Bell is a logarithmic unit used to represent the degree of sound intensity at a certain location. The ratio of sound intensity at a given point to threshold intensity sound is the sound intensity level at that point.
Sound intensity is measured in terms of power per unit area. Assume that the sound is emitted in a spherical pattern from the loudspeaker.
