Decibel readings in problem use the fact that the loudness

Question: Decibel readings in Problem 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.

The background noise level of a relatively quiet room is about L₁ = 32 decibels and of a heated argument is about L₂ = 66 decibels. Find the ratio I₂/I₁ of the associated intensities.
