db is an objective unit, and phon is a subjective unit.

This means that db measures the actual pressure of the sound waves, and phon measures the perceived sound as heard from human ears.

The units are very closely related, and under certain situations, phon is the same as db.

But since the human ear may hear different frequencies differently, phon my differ from db in certain situations.
