The sound level b in decibels is given by b= 10 log (I/ lo), where lis the intensity of a given sound and Io is the minimum detectable intensity. How many times more intense is the sound of a typical food processor at 89 decibels compared to a that of a typical alarm clock at 71 decibels? [Hint: set up a ratio of intensities as shown on Example 5, p. 392.] Show all work.
