This type of stuff is also good for training ears, so to say. Very similar to photography or such. When taking photo, all looks good, realizing later on, there is something utterly unwanted element in it.
Same for a lot of field recordings, where you brain says, absolutely brilliant screeching sound of excavator track chains that would be like... The New Blockaders. Full of tiniest details of screech, clatter, crunch, stones being crushed under them... That's what I have been hearing a lot this summer. Then, as soon as you think lets record this as source sound, it is most likely you suddenly realize the dull sound of excavators engine, traffic lights beeping, heavy traffic all around, people talking... all sorts of things your brain certainly ignored, but recorder did not.
I think they were talking about something like this in early year field recording episodes of Noisextra podcast? The difference of intentionally out there recording something... but the recorder captures everything. Therefore you may actually hear the sound first time when listening the recording. At location, it was your own focus and attention what prioritized things that may have been just one small element in massive environment of sound.
I suppose there are more technical topics about how to try solve something like this.
