We were at FL360 and heard a couple of loud booms. The noise and vibration made it obvious the engine stalled or we hit something. I looked at the engine instruments and saw the #2 egt and N1 winding down. I told the first officer to pull the throttle to idle. I told the first officer to fly the airplane and I would work the problem. He said that we could not hold altitude; so I called ATC and requested a lower altitude. ATC issued FL240 and we started a descent. We initiated the qrc for engine stall; then got out the manual for the irregular procedure. In the procedure; we increased the #2 thrust lever to climb power (this was at approximately FL270) and nothing happened. The first officer pointed out that the power was at idle. I increased the speed to something higher and as the power was increased; we heard the loud 'boom; boom' again. Then we pulled the thrust lever back to idle. When we initially called ATC; they had suggested that ZZZ1 and ZZZ were the closest airports. Now I requested ZZZ WX from ACARS and requested dispatch call me. The ZZZ WX was VFR and dispatch called. I told him of our situation and that we were going to divert into ZZZ. He reiterated the ZZZ WX and that he would advise ZZZ operations of our arrival. While I was doing this; I told the first officer to declare an emergency and call for the trucks. The flight attendant had called after the first stall and thought we had a yaw damper problem. I told her that it was an engine and that I would call her back. So after talking to dispatch; I called the flight attendant and told her that we had an engine shutdown and were diverting into ZZZ. I asked her to do an advisory; that it would probably be a normal landing; and we would be on the ground in approximately 15 mins. At this time we got busy with the descent. It was mostly uneventful from there except we were a little high on approach and had to do some s-turns on final to get down. We landed on runway 9 and rolled out almost to the end.

Title: A320 DIVERTS TO NEAREST ARPT FOLLOWING COMPRESSOR STALLS AND SHUTDOWN OF RIGHT ENGINE.
Narrative: WE WERE AT FL360 AND HEARD A COUPLE OF LOUD BOOMS. THE NOISE AND VIBRATION MADE IT OBVIOUS THE ENG STALLED OR WE HIT SOMETHING. I LOOKED AT THE ENG INSTS AND SAW THE #2 EGT AND N1 WINDING DOWN. I TOLD THE FO TO PULL THE THROTTLE TO IDLE. I TOLD THE FO TO FLY THE AIRPLANE AND I WOULD WORK THE PROB. HE SAID THAT WE COULD NOT HOLD ALT; SO I CALLED ATC AND REQUESTED A LOWER ALT. ATC ISSUED FL240 AND WE STARTED A DSCNT. WE INITIATED THE QRC FOR ENG STALL; THEN GOT OUT THE MANUAL FOR THE IRREGULAR PROC. IN THE PROC; WE INCREASED THE #2 THRUST LEVER TO CLB PWR (THIS WAS AT APPROX FL270) AND NOTHING HAPPENED. THE FO POINTED OUT THAT THE PWR WAS AT IDLE. I INCREASED THE SPD TO SOMETHING HIGHER AND AS THE PWR WAS INCREASED; WE HEARD THE LOUD 'BOOM; BOOM' AGAIN. THEN WE PULLED THE THRUST LEVER BACK TO IDLE. WHEN WE INITIALLY CALLED ATC; THEY HAD SUGGESTED THAT ZZZ1 AND ZZZ WERE THE CLOSEST ARPTS. NOW I REQUESTED ZZZ WX FROM ACARS AND REQUESTED DISPATCH CALL ME. THE ZZZ WX WAS VFR AND DISPATCH CALLED. I TOLD HIM OF OUR SITUATION AND THAT WE WERE GOING TO DIVERT INTO ZZZ. HE REITERATED THE ZZZ WX AND THAT HE WOULD ADVISE ZZZ OPS OF OUR ARR. WHILE I WAS DOING THIS; I TOLD THE FO TO DECLARE AN EMER AND CALL FOR THE TRUCKS. THE FLT ATTENDANT HAD CALLED AFTER THE FIRST STALL AND THOUGHT WE HAD A YAW DAMPER PROB. I TOLD HER THAT IT WAS AN ENG AND THAT I WOULD CALL HER BACK. SO AFTER TALKING TO DISPATCH; I CALLED THE FLT ATTENDANT AND TOLD HER THAT WE HAD AN ENG SHUTDOWN AND WERE DIVERTING INTO ZZZ. I ASKED HER TO DO AN ADVISORY; THAT IT WOULD PROBABLY BE A NORMAL LNDG; AND WE WOULD BE ON THE GND IN APPROX 15 MINS. AT THIS TIME WE GOT BUSY WITH THE DSCNT. IT WAS MOSTLY UNEVENTFUL FROM THERE EXCEPT WE WERE A LITTLE HIGH ON APCH AND HAD TO DO SOME S-TURNS ON FINAL TO GET DOWN. WE LANDED ON RWY 9 AND ROLLED OUT ALMOST TO THE END.
