28. Decibels are units used to measure sound. The softest sound that can be heard is rated as
0 decibels (or a relative loudness of 1). Ordinary conversation is rated at about 60 decibels (or
a relative loudness of 106). A rock concert is rated at about 120 decibels (or a relative loudness
of 1012). How many times greater is the relative loudness of a rock concert than the relative
loudness of ordinary conversation? 106 or 1,000,000 times
