Question: The sound level b in decibels is given by b = 10 log (I / Io), where I is the intensity of a given sound

The sound level b in decibels is given by b = 10 log (I / Io), where I is 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 86 decibels compared to that of a typical alarm clock at 70 decibels?
