An equation for the loudness of L a sound in decibels is L = 10 log R, where
R is the relative intensity of the sound. The loudness of a chainsaw is about 120
decibels. The loudness of a handsaw is about 85 decibels. How can you determine how
many times greater the intensity of the chainsaw is than the intensity of the handsaw?
Determine how many times greater the intensity of the chainsaw is than the intensity
of the handsaw.
