The air density increases and decreases repeatedly before returning to normal.

Explanation: A ringing bell produces longitudinal sound waves (compressions and rarefactions). That causes alternating regions of higher and lower air density as the wave passes; after the waves pass (or dissipate), the density returns to the ambient value.
