Unformatted text preview: 1 p p from dB IL = 10 log 1 I I . Hint: Use the relation p 2 I . Start with the equation for dB IL, and substitute I by p 2 . So the first step would be dB SPL = 10 log ( ) ( ) 2 2 1 p p . This is the same as 10 log 2 1 p p , which is the same as 10 x 2 log 1 p p , which is 20 log 1 p p...
