Decibel intensity problem

  1. Sep 20, 2014 #1
    What is the decibel level of a sound whose intensity is 4% that of a 95dB sound?

    I know dB = 10log(I/Io) but don't know how to incorporate this for this question.

    Look at incorporating the percent to the I in the formula and then use log rules to pull out the percent factor.
