Question:
Decibel rating of the loudness of a sound is modeled by
where I is the intensity of a particular sound, and I0 is the intensity of a very faint threshold sound. A few years ago, there was a controversy about a proposed government limit on factory noise. One group wanted a maximum of 89 decibels, while another group wanted 86. Find the percent by which the 89-decibel intensity exceeds that for 86 decibels.
