The decibel level of a snowmobile is approximately 105 decibels. Find the sound intensity of the snowmobile at the registered decibel level. Express its intensity in terms of the reference intensity, that is, I0. I0 Solution 10 log(I/I0) =105 dB log (I/I0)=10.5 (I/Io) = (3.162*10^10) I =(3.162*10^10) Io.
