An air pump is outside the tank, forcing air into the tank through the airline. Pumps, fans and powerheads are all inside the tank, moving water. If you are concerned about oxygenation, many powerheads have attachments to inject air bubbles into the water flow.
Air stones require an air pump - they go hand in hand.
IME, visitors are always pleasantly surprised at the lack of noise made by my aquariums (I don't own an air pump). They always complain about the noise made by other peoples tanks. for what it's worth.
