Narrative:

Prior to departing san jose on sep/fri/89, we (the captain and myself) received the company printout of our flight plan from san jose (sjc) to chicago (ord). The departure indicated a sunol 3 SID with a sacramento transition. We programmed the appropriate navigation radios, setting frequencys, courses and altitudes while briefing the departure procedures. Later during our cockpit duties, I called for a clearance and in accordance with company policy and procedures. Both the captain and I monitored the clearance and I read back what we were given. Ironically, the clearance received and what I read back was a loupe 6 departure. At the time of the clearance there was a great deal of noise and distraction from the front of the cabin from last minute boardings and noise from the galley area. We were using the aircraft overhead speakers and as we set the assigned transponder code we realized that the code we understood to have received began with a 12 indicating a VFR code. I called clearance deliver to verify our code at which time they gave us a correct IFR code. We backed off the gate, completed our checks and took off on a sunol 3 departure. As we made VOR turn to 040 degree, san jose departure asked us what heading we were on and we stated 040 degree. They asked us to turn to a heading of 150 degree and asked us what departure we were flying. Of course we told them we were on the sunol 3. The controller correctly stated we should be on the loupe 6 and assigned vectors to established us the correct departure. We reestablished on the loupe 6 and the remainder of the flight proceeded uneventful.
