I worked in an office that had floor to ceiling windows, and a when a construction project started down the street there was some equipment they'd occasionally run that produced infrasound matching the resonance of my office. When it was running, being in the office felt similar to the beating that sometimes happens when driving on the freeway with a car window open, but without the wind and much stronger. It was impossible to get any work done while that happened, but fortunately it wasn't very often.
Smaller rooms are really good at avoiding this problem. If you can get a bed or desk to fit in a closet that is <2 meters square, you are not going to resonate with anything under 100hz. Frequencies above this level become significantly easier to filter out.
