Narrative:
While conducting the loop 9 departure, in the climbing turn to 120 degrees climbing to 5000 ft, we heard and replied to a clearance for another aircraft. Departure did not correct our readback. All our radio calls were prefaced with our full call sign. Both crew members heard our call sign, with the clearance, on the first call. The intended aircraft questioned bay departure that they were not hearing call signs from departure. Departure provided vectors for the departure. Even with increased attention on our part there was continued confusion on our clearance. Departure claimed we missed a frequency change, and changed us to 119.74. We read back 119.74 and again he failed to correct the error. Our call sign ended in xa, the frequency was 119.47. It is just as important for a controller to listen to a full readback as it is for crew members to be attentive to radio calls. The frustration and confusion could have been minimized had the controller corrected the initial wrong radio call and slowed down with his xmissions.

Title: FLC OF A B757-200 RESPONDED TO ANOTHER ACFT'S CALL SIGN DURING A DEP SID AND THE CTLR DID NOT NOTICE ERROR ON THEIR ACKNOWLEDGEMENT ON SEVERAL OCCASIONS DURING THE READBACK OF THEIR CLRNCS.
Narrative: WHILE CONDUCTING THE LOOP 9 DEP, IN THE CLBING TURN TO 120 DEGS CLBING TO 5000 FT, WE HEARD AND REPLIED TO A CLRNC FOR ANOTHER ACFT. DEP DID NOT CORRECT OUR READBACK. ALL OUR RADIO CALLS WERE PREFACED WITH OUR FULL CALL SIGN. BOTH CREW MEMBERS HEARD OUR CALL SIGN, WITH THE CLRNC, ON THE FIRST CALL. THE INTENDED ACFT QUESTIONED BAY DEP THAT THEY WERE NOT HEARING CALL SIGNS FROM DEP. DEP PROVIDED VECTORS FOR THE DEP. EVEN WITH INCREASED ATTN ON OUR PART THERE WAS CONTINUED CONFUSION ON OUR CLRNC. DEP CLAIMED WE MISSED A FREQ CHANGE, AND CHANGED US TO 119.74. WE READ BACK 119.74 AND AGAIN HE FAILED TO CORRECT THE ERROR. OUR CALL SIGN ENDED IN XA, THE FREQ WAS 119.47. IT IS JUST AS IMPORTANT FOR A CTLR TO LISTEN TO A FULL READBACK AS IT IS FOR CREW MEMBERS TO BE ATTENTIVE TO RADIO CALLS. THE FRUSTRATION AND CONFUSION COULD HAVE BEEN MINIMIZED HAD THE CTLR CORRECTED THE INITIAL WRONG RADIO CALL AND SLOWED DOWN WITH HIS XMISSIONS.
