In addition to these answers, I'd say that most of the time it is unlikely that the stomping will go away completely. As a result, in the future you must try to get a top floor apartment. As a last, I recommend getting a bluetooth speaker with bass, but not turned up high. Listen to"Rumble Works - Ambient Low Frequency Noisescape for Ten Hours" on youtube with bass about 50%. It is good at masking the stomps. Stomps are low frequency sounds so you need low frequency noise to effectively mask it. — Jarvis 12 secs ago
