Oh boy, after flying the Airbus for a good number of years, im now in the 737 and its frankly quite bad in that regard. Not sayin the bus is a good system but the 737.....
A lot of the flight deck noise on Boeing aircraft is due to the ECS. I'd even heard Boeing test pilots who'd flown Airbus aircraft comment on how much better the flight deck ECS noise is on Airbus.
The 777 flight deck windows are basically flat - that section of the airframe ("41 Section" in Boeing speak) is common between the 757, 767, and 777. The 787 flight deck has curved windows and is aerodynamically cleaner than the 777 which would improve the flight deck noise - although I can't quantify that.
