In decibels, the sound intensity is 
dB.
The sound intensity reference level is 
.
Formula used:
The definition of intensity for a sound wave is the same as it was for other waves; it is
where 
is the output power and area is the 
.
Sound intensity is measured in decibels (dB):
where is the sound intensity and 
is the sound intensity reference level.
Step-by-step explanation
Step 1.
Find the intensity from the
-dB value, and then the power output at that distance from the speaker that corresponds to that intensity.
