400MPH with an open window plausibly causes some loud noise due to turbulent flow across the opening. The turbofan engines are also reasonably close to the opening and ground crew wear hearing protection to mitigate the effects of the noise.
- baq 3y agoMy assumption was that the air pressure at that height is low enough to not be loud. Yeah it’s moving fast but there isn’t much of it. Different story on the ground.
- rainbowzootsuit 3y agoThat's a good thought. Initially the density is pretty normal and I'm sure there's a loud sound, but once pressure drops the air wouldn't transmit as much sound. I don't see enough detail to really know how high they fly once the depressurization happens. I'm guessing that, if possible, they descend to an altitude where the supplementary oxygen is not critical for preserving life so the loudness could go back up. I couldn't find if there's a "typically safe" maximum altitude that is used in depressurization or it's situational. Probably someone with better flightradar knowledge could figure out the altitude with time.
