Narrative:
After takeoff from hya on a single pilot part 135 charter in a C402 I was instructed to climb to 4000 ft and turn to a heading of 270 degrees. As I was climbing I was then instructed to turn to 240 degrees and join V167 to pvd. At this time I was supposedly told to turn to a heading of 280 degrees but I never heard the instruction for some reason I do not know. I believe the controller tried to contact me a few times because when I finally heard the instruction, it was a different controller (I believe it was a supervisor), telling me to turn to 280 degrees immediately. I acknowledged this instruction and turned. The controller seemed a little perturbed and mentioned that I should listen and respond to his instructions in a more timely manner. I wanted to tell him that I never heard the first 2 or 3 radio calls and that was why I never turned or acknowledged his xmissions, but it seemed he was very busy and wasn't interested in my explanation. A few mins later I was given a frequency change to pvd approach and completed the flight, never knowing why I was told to turn to 280 degrees anyway.

Title: C402 CHARTER PLT ON IFR FLT FAILS TO HEAR ATC INSTRUCTION TO TURN. SECOND CTLR TAKES OVER AND GETS HIS ATTN.
Narrative: AFTER TKOF FROM HYA ON A SINGLE PLT PART 135 CHARTER IN A C402 I WAS INSTRUCTED TO CLB TO 4000 FT AND TURN TO A HDG OF 270 DEGS. AS I WAS CLBING I WAS THEN INSTRUCTED TO TURN TO 240 DEGS AND JOIN V167 TO PVD. AT THIS TIME I WAS SUPPOSEDLY TOLD TO TURN TO A HDG OF 280 DEGS BUT I NEVER HEARD THE INSTRUCTION FOR SOME REASON I DO NOT KNOW. I BELIEVE THE CTLR TRIED TO CONTACT ME A FEW TIMES BECAUSE WHEN I FINALLY HEARD THE INSTRUCTION, IT WAS A DIFFERENT CTLR (I BELIEVE IT WAS A SUPVR), TELLING ME TO TURN TO 280 DEGS IMMEDIATELY. I ACKNOWLEDGED THIS INSTRUCTION AND TURNED. THE CTLR SEEMED A LITTLE PERTURBED AND MENTIONED THAT I SHOULD LISTEN AND RESPOND TO HIS INSTRUCTIONS IN A MORE TIMELY MANNER. I WANTED TO TELL HIM THAT I NEVER HEARD THE FIRST 2 OR 3 RADIO CALLS AND THAT WAS WHY I NEVER TURNED OR ACKNOWLEDGED HIS XMISSIONS, BUT IT SEEMED HE WAS VERY BUSY AND WASN'T INTERESTED IN MY EXPLANATION. A FEW MINS LATER I WAS GIVEN A FREQ CHANGE TO PVD APCH AND COMPLETED THE FLT, NEVER KNOWING WHY I WAS TOLD TO TURN TO 280 DEGS ANYWAY.
