Narrative:
Flight crew flew SID for which we thought we had been cleared (sunol 4-SJC). First officer took clearance. I listened and thought I heard sunol 4 on clearance. First officer thought that the sunol 4 was the right SID--even the computerized flight plan had the sunol 4 on it and we thoroughly briefed the departure. The first officer did write down the clearance as the loupe 6-SJC, but we both became fixed on the sunol 4--possibly because of noise in cockpit, my suggestion that the sunol 4 would be our clearance, or the flight plan showing sunol 4. At any rate, we briefed and flew the sunol 4 SID, until vectored back to the loupe 6 by bay TRACON.

Narrative: FLT CREW FLEW SID FOR WHICH WE THOUGHT WE HAD BEEN CLRED (SUNOL 4-SJC). F/O TOOK CLRNC. I LISTENED AND THOUGHT I HEARD SUNOL 4 ON CLRNC. F/O THOUGHT THAT THE SUNOL 4 WAS THE RIGHT SID--EVEN THE COMPUTERIZED FLT PLAN HAD THE SUNOL 4 ON IT AND WE THOROUGHLY BRIEFED THE DEP. THE F/O DID WRITE DOWN THE CLRNC AS THE LOUPE 6-SJC, BUT WE BOTH BECAME FIXED ON THE SUNOL 4--POSSIBLY BECAUSE OF NOISE IN COCKPIT, MY SUGGESTION THAT THE SUNOL 4 WOULD BE OUR CLRNC, OR THE FLT PLAN SHOWING SUNOL 4. AT ANY RATE, WE BRIEFED AND FLEW THE SUNOL 4 SID, UNTIL VECTORED BACK TO THE LOUPE 6 BY BAY TRACON.
