This is a specific question. My workplace is located in a poorly constructed building and there's an office above me, where people occasionally stomp. The worst part is heeled shoe women loudly stomping on some parts of their floor (my ceiling), where the entire room just booms loud. There's also the annoying heel loud click, but it is not so severe and can be drowned with music.
I could not manage to get along with these assholed people, so my only option is to move or somehow kill that bass resonance. It seems to be at a specific frequency, so I wondered if a Helmholtz resonator tuned at that specific frequency might help absorbing this frequency peak?

Can a Helmholtz resonator cure your footfall induced room boom? You would need a large one to be effective at low frequencies and it could occupy much of your room. The bandwidth of a resonator is narrow and it would be unlikely to 'suck out' enough of the annoying sound which probably has a wider spectrum than you think. Try opening a window instead. 🙂
🙂 make sure the holes go right through to their office before spraying the foam... maybe stick their feet to the floor...
As Galu said, it's unlikely you could solve this with a resonator.

Now you know why post WWII when they built new apartment buildings they carpeted the floors.
To absorb low frequencies the normal approach is to use loose heavy fabric. This is called diaphragmatic absorption. So the question becomes what is your ceiling? Can you get in there and see the floor above?
If not the next step is to look for any cracks or holes, those must be filled.
Instead of a resonator you can hang heavy drapes, large canvas paintings or similar.

I can envision a few tactile transducers and speakers screwed to your ceiling with a big power amp. Have low frequency pulses and the sound effect of a crackling ceiling ready to play as soon as they stomp.
