## Discrepancy

F/A REPORTS LOUD PRESSURE LEAK AT FWD JUMPSEAT, LOUDEST MIDWAY BETWEEN 1L AND 1R.  FLT ATTD NOTICED A HUM AT 10,000 FT, WHEN SHE GOT THE 2 DINGS FROM FLT DECK, THAT ITS OK FOR HER TO GET UP.  SITTING DOWN SHE COULD NOT HEAR THE HUM.  HUM IS COMING FROM TOP OF A-C, BY 2000VU CB PNL.  HUM WENT AWAY AS AIRCRAFT SPEEDED UP.  SHE SAID, THAT IT WAS THE LOUDEST AT CTR OF A-C AND GOT LESS AS YOU WENT TO DOOR 1L AND 1R. IT DID NOT SOUND LIKE A DOOR LEAK.  NUMBER ONE VHF ANTENNA GIVES HOWL FROM CF0315.  NOISE NOTICEABLE BTWN 240-270 KNOTS 35,000FT.  REPLACED THE NR 1 (TOP) VHF ANTENNA IAW AMM.
