Narrative:
I was the first officer and PF. In cruise flight at FL370, there was a loud 'pop' and I looked up to find my forward windshield shattered. I put on my oxygen mask/goggles, and the captain did the same. He requested lower, and ATC cleared us to FL330. I recommended we declare an emergency and land as soon as possible, and the captain then did declare an emergency and stated our intention to land in jax. I ran the checklist for cracked windshield while the captain flew the aircraft. I had xferred control to him, since I could not see out the windshield. As we descended and the differential psi became less, glass fragments began falling in from the windshield. I suggested keeping a 1 psi pressure to keep an outward force on the windshield, which we then did by going to manual pressure control. Arriving for a visual on runway 7 at jax, we were high and fast, so the captain elected to go around. We did a visual pattern and landed without incident. At the gate, closer inspection by maintenance revealed that it was only the inner layer of the windshield that had failed.

Title: A319 EXPERIENCES LOUD POP ACCOMPANIED WITH WINDSCREEN BREAKING. DIVERT TO JAX AFTER DECLARING EMER.
Narrative: I WAS THE FO AND PF. IN CRUISE FLT AT FL370, THERE WAS A LOUD 'POP' AND I LOOKED UP TO FIND MY FORWARD WINDSHIELD SHATTERED. I PUT ON MY OXYGEN MASK/GOGGLES, AND THE CAPT DID THE SAME. HE REQUESTED LOWER, AND ATC CLRED US TO FL330. I RECOMMENDED WE DECLARE AN EMER AND LAND ASAP, AND THE CAPT THEN DID DECLARE AN EMER AND STATED OUR INTENTION TO LAND IN JAX. I RAN THE CHKLIST FOR CRACKED WINDSHIELD WHILE THE CAPT FLEW THE ACFT. I HAD XFERRED CTL TO HIM, SINCE I COULD NOT SEE OUT THE WINDSHIELD. AS WE DSNDED AND THE DIFFERENTIAL PSI BECAME LESS, GLASS FRAGMENTS BEGAN FALLING IN FROM THE WINDSHIELD. I SUGGESTED KEEPING A 1 PSI PRESSURE TO KEEP AN OUTWARD FORCE ON THE WINDSHIELD, WHICH WE THEN DID BY GOING TO MANUAL PRESSURE CTL. ARRIVING FOR A VISUAL ON RWY 7 AT JAX, WE WERE HIGH AND FAST, SO THE CAPT ELECTED TO GO AROUND. WE DID A VISUAL PATTERN AND LANDED WITHOUT INCIDENT. AT THE GATE, CLOSER INSPECTION BY MAINT REVEALED THAT IT WAS ONLY THE INNER LAYER OF THE WINDSHIELD THAT HAD FAILED.
