The Decibel Scale
The decibel scale is used to express the ratio between two values of a physical quantity, in this case, sound intensity
We use the equation \(L_p\)= 20 log10\(\frac{prms}{pref}\) to calculate this ratio is decibels
Where Prms = is the sound pressure being measured and Pref = the reference pressure
To the right is a scale showing how loud certain values on the decibel scale are.
