Reporter receives TA and TCASII RA. ATC was notified by the reporter they were turning and descending to avoid the traffic. The reporter could hear the engine noise of the traffic which was a baron.

Narrative:
Nyc gave us a TA 12 O'clock at 5-6 NM at 17500 ft. I received a TCASII TA (yellow box at 12 O'clock at 5 NM). I told first officer to tell ATC we were turning to the right. I received an RA 'monitor vertical descent.' I went down to 16700 ft. The aircraft flew overhead (twin baron I think) very loud engine noise. TCASII 'clear of conflict.' I returned to 17000 ft and informed ATC of the situation. Why would ATC allow an IFR aircraft to be heading at a VFR aircraft with 500 ft separation? If both aircraft have the same altimeter setting, you miss by 500 ft but wrong altimeter setting or off altimeter could be close. Poor procedure!
Original NASA ASRS Text
Title: RPTR RECEIVES TA AND TCASII RA. ATC WAS NOTIFIED BY THE RPTR THEY WERE TURNING AND DSNDING TO AVOID THE TFC. THE RPTR COULD HEAR THE ENG NOISE OF THE TFC WHICH WAS A BARON.
Narrative: NYC GAVE US A TA 12 O'CLOCK AT 5-6 NM AT 17500 FT. I RECEIVED A TCASII TA (YELLOW BOX AT 12 O'CLOCK AT 5 NM). I TOLD FO TO TELL ATC WE WERE TURNING TO THE R. I RECEIVED AN RA 'MONITOR VERT DSCNT.' I WENT DOWN TO 16700 FT. THE ACFT FLEW OVERHEAD (TWIN BARON I THINK) VERY LOUD ENG NOISE. TCASII 'CLR OF CONFLICT.' I RETURNED TO 17000 FT AND INFORMED ATC OF THE SIT. WHY WOULD ATC ALLOW AN IFR ACFT TO BE HDG AT A VFR ACFT WITH 500 FT SEPARATION? IF BOTH ACFT HAVE THE SAME ALTIMETER SETTING, YOU MISS BY 500 FT BUT WRONG ALTIMETER SETTING OR OFF ALTIMETER COULD BE CLOSE. POOR PROC!
