Narrative:
Cruising at 35;000 ft with clearance to 30;000 ft the first officer initiated the descent using the FMGC. As we started the descent a loud bang; as in loss of cabin pressure and decompression in my mind; accompanied with loud noise and surges in pressurization. I took the aircraft told the first officer to tell the center we possibly had lost cabin pressure and needed 10;000 ft. We were cleared to 15;000 ft initially; we donned oxygen masks and ran the QRH. The cabin altitude initially climbed slowly to 8;800 ft in yellow; as we continued the descent the cabin alt stopped climbing and started to go down. As we descended through 18;000 ft the cabin altitude was 5;500 ft at 12;000 ft the cabin was secure we removed our masks. We clarified our emergency with ATC; let the passengers know and the first officer landed the aircraft without incident.
