Effect of door on room acoustics

[slartibartfast]

I haven't paid attention to this before but I measured raw room response with a door halfway along the left wall closed and half open. The biggest difference seems to be in the left channel around 200Hz.
First left channel
Red = door half open
Blue = door closed

Right channel
Grey = door half open
Brown = door closed

There's also the precise observation ...with you... or not (without an audience)... in the room...
"The spirit of the room"

Just a joke

The impact of open/closed room on bass response can sometimes be quite significant. Have a look at this.

Whenever a door is closed, a window is opened?
(See what I did there?)

The result is I created 3 different EQ presets that I have to switch depending on the door/window position!



I made the same experience: by opening my large sliding window (3m) the bass is practically sucked out of the room…

What would the settings be for when there's nobody in the room, I wonder

If a man speaks alone in the forest with no woman to hear, is he still wrong?

An IMHO interesting observation in this hobby: comparing the sound of e.g. DACs and cables seems to be considered normal behaviour - even though there's no real evidence that this can bring any benefit, and the exercise costs both money and time.
On the other hand adjusting for changes in room acoustics when opening a door is implied to be going too far - even when demonstrating an example where there's an almost 10dB difference in one part of the spectrum, and the adjustment costs no money (just a little time).

Audiophiles are weird.

Joking aside, in my experience not every room is subject to this effect to the same extent - in some rooms just a single correction can absolutely work well enough. Unfortunately that doesn't seem to be the case for every room.

A preset for an open or closed room wouldn't be so questionable after all... just a click
(if significant differences are observed above 50Hz for example)
;-)

I agree.
