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.

My encounter with low frequency noise was just a high speed lift audible from the flat, but it made me realize I strictly want to avoid this in future. The lower you go, the more unsuppressable[0] the sound gets, and at some point you start feeling more than hearing it.

[0] You need material as thick as the wave is long, although allegedly there have been papers investigating the use of metamaterials that are much thinner—presumably for military use by subs—there is nothing commercially available yet.

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.
