Narrative:
Both events were with the new raas. After pushback and beginning to taxi while transitioning from alpha to bravo; the raas announced approaching xxl which cause ATC to be partially blocked while they were telling us to hold short of taxiway for an aircraft exiting the runway. Luckily; I saw the aircraft because it was clear out. I repeated hold short assuming the call was for us. Had it been an IFR day; the raas would have caused a lot of confusion due to interrupting the ground controller. The second occasion was while holding in position for takeoff on runway xxl. The tower; we assumed; cleared the aircraft on runway yl for takeoff. We couldn't hear the full radio call because raas was so loud in the cockpit we could not hear the full ATC clearance. This caused us to temporarily loose situational awareness because of this new technology being too loud. I think this is a great technology; but the volume issue must be addressed. Let's not have a runway incursion caused from the new runway incursion system.
