I’m sitting in my house and just closed a window – 3 metres away on the other side of the room, the door rattled and then opened as a result of me closing the window. Can someone explain how shutting the window shook and opened the door on the other side?
Thanks

Air pressure. My house has really weird pressure. I can close a door on one end of the house, and if the garage door isn’t latched right, it’ll open and then SLAM shut.
> just closed a window (…) the door rattled
That shouldn’t happen, unless you’re leaving something out or missed the sequence of events.
Usually, shutting a door can rattle a window, but not the other way around, because doors swing and windows merely close.
It’s air pressure. When a door swings closed, it’s pushing air in front of it, which can increase or decrease pressure in a room. That, in turn, affects the ratio of internal and external air pressure on a window, causing it to rattle.
