Narrative:

Turning final approach to runway xx (approximately 2500 ft MSL) multiple ECAM indications occurred including the following: 1) door right aft cabin. 2) cabin pressure low differential pressure. 3) door left aft cabin. 4) cabin pressure safety valve open. Cabin pressurized and differential pressure went to 0 psi and I could physically feel the aircraft depressurize. Captain; pilot monitoring; contacted flight attendant in aft cabin. Flight attendant said everything appeared normal at the door stations. Captain told flight attendants to remain seated and buckled up and not approach the doors till on the ground. Aircraft confign was completed for landing and normal landing and rollout followed. After landing; all ECAM indications and cautions reverted to normal as we taxied in. Aircraft parked at gate and all doors disarmed and operated normally. Logbook entry made and maintenance contacted.

Narrative: TURNING FINAL APCH TO RWY XX (APPROX 2500 FT MSL) MULTIPLE ECAM INDICATIONS OCCURRED INCLUDING THE FOLLOWING: 1) DOOR R AFT CABIN. 2) CABIN PRESSURE LOW DIFFERENTIAL PRESSURE. 3) DOOR L AFT CABIN. 4) CABIN PRESSURE SAFETY VALVE OPEN. CABIN PRESSURIZED AND DIFFERENTIAL PRESSURE WENT TO 0 PSI AND I COULD PHYSICALLY FEEL THE ACFT DEPRESSURIZE. CAPT; PLT MONITORING; CONTACTED FLT ATTENDANT IN AFT CABIN. FLT ATTENDANT SAID EVERYTHING APPEARED NORMAL AT THE DOOR STATIONS. CAPT TOLD FLT ATTENDANTS TO REMAIN SEATED AND BUCKLED UP AND NOT APPROACH THE DOORS TILL ON THE GND.
