I but ialso would like to be shown how to get the ratio as the answer inthe end.
An amplified guitar has a sound intensity lvl that is 12.2 dBgreater than the same unamplified sound. What is the ratio of theamplified intensity to the unamplified intensity?

Explanation / Answer

Given : The amplified sound intensity level (2 ) is 12.2 dB greater than un-amplified soundintensity level ( 1 )         2 - 1 = 12.2 dB If the intensities of sound for amplified andun-amplified are I2 W / m2 and I1 W / m2then       2 -1 = ( 10 ) dB log ( I2 / I1)      log ( I2 /I1 ) = ( 12.2 dB ) / ( 10 dB )                  I2 / I1 = 101.22    Required ratio ( I2 / I1 )= 16.6    I hope it helps you    Required ratio ( I2 / I1 )= 16.6    I hope it helps you
