The background noise level of a relatively quiet room is about L1 = 32 decibels and of a heated argument can exceed L2 = 66 decibels. Find the ratio I2 / I1 of these associated intensities.
Use the fact that the loudness of sound (in decibels) perceived by the human ear depends on intensity levels according to L = 10 log(I / I0) where I0 is the threshold of hearing for the average human ear.
