Operated 737-MAX; ZZZ-ZZZ1. CA (Captain) wearing noise canceling headset. FO (First Officer) wearing clarity aloft noise cancelling headset.Approaching Runway XXR RAAS announced (very loudly) 'approaching Runway XXR'. At the exact same time tower told us to 'line up and wait'. Both pilots could not hear the ATC instruction and ATC had to repeat. This exact same thing happened again with the takeoff clearance. As we lined up on Runway XXR RAAS announced 'on Runway XXR' at the exact same time Tower said 'clear for takeoff'. I could hear that Tower was transmitting but it was impossible to hear what was actually being said.Picture trying to have a private conversation with someone and another person jumps in and starts yelling directly in your ear.
B737 MAX Captain reported RAAS annunciations are extremely loud resulting in blocked or interrupted communications.
