Narrative:
Departing hpn on takeoff leg we had a TA from ATC followed by a TA and RA. This was on climb out to 2000 ft with traffic at 2 O'clock at 2500 ft. On the changeover to ny departure control, the TCASII RA volume was so loud we were unable to understand any further ATC clrncs or instructions during an absolutely critical phase of flight. While TCASII fortunately had altitude information and we had 500 ft vertical separation, this was a very unsettling experience. It is also not the first time I have had TCASII volume interfere with the accomplishment of cockpit duties. The system is much too loud, this is unacceptable and needs to be evaluated. The sound level is way too high.

Title: THE RPTR WAS UNABLE TO HEAR TFC CTL INSTRUCTIONS WITH THE LOUDNESS OF THE TCASII RA AND TA ADVISORIES.
Narrative: DEPARTING HPN ON TKOF LEG WE HAD A TA FROM ATC FOLLOWED BY A TA AND RA. THIS WAS ON CLBOUT TO 2000 FT WITH TFC AT 2 O'CLOCK AT 2500 FT. ON THE CHANGEOVER TO NY DEP CTL, THE TCASII RA VOLUME WAS SO LOUD WE WERE UNABLE TO UNDERSTAND ANY FURTHER ATC CLRNCS OR INSTRUCTIONS DURING AN ABSOLUTELY CRITICAL PHASE OF FLT. WHILE TCASII FORTUNATELY HAD ALT INFO AND WE HAD 500 FT VERT SEPARATION, THIS WAS A VERY UNSETTLING EXPERIENCE. IT IS ALSO NOT THE FIRST TIME I HAVE HAD TCASII VOLUME INTERFERE WITH THE ACCOMPLISHMENT OF COCKPIT DUTIES. THE SYS IS MUCH TOO LOUD, THIS IS UNACCEPTABLE AND NEEDS TO BE EVALUATED. THE SOUND LEVEL IS WAY TOO HIGH.
