Sound intensity is a factor of amplitude and distance from the source. It's a measure of acoustical energy per unit area. The human ear is not as sensitive to all frequencies. It is most sensitive around 1-3 KHz (depending on if you're a man or woman). When we consider the person's reaction to the sound intensity, we call it loudness. Loudness is a factor of amplitude, frequency and distance from the source. It is sometimes difficult to understand the difference, although it's quite simple. Sound intensity is a purely scientific measurement whereas loudness is a subjective measurement.

Ehh, its only a factor of distance insofar as amplitude decreases with distance. Its easier to just say amplitude (especially since he didn't ask about distance).
